My Sister is Very Obsessive

Although I was disturbed by the auntie, I didn't feel annoyed, but more embarrassed. My sister is thin-skinned and can hide behind me with her head down, but I have nowhere to hide, so it's best The countermeasure is to walk.

I dragged my sister and ran for a long distance until I turned around and couldn't see the girls' dormitory hugging me, so I stopped.

Needless to say, my sister, who is extremely lacking in exercise on weekdays, looked at her with her hands on her chest and gasping for breath, I felt distressed and took her into my arms, gently stroked her back, and helped her. Go with the breath.

"You, you have to exercise."

"Don't!" My sister bent her hands and leaned on my chest, her small mouth exhaling hot air against my chest, "I'm exhausted, don't go."

"No, starting tonight, I'll accompany you to the playground to run laps."

My sister looked at me with a pleading expression on her lips, I poked her forehead with my finger, and said firmly, "Don't refuse."

"Are you serious?" My sister blinked at me and looked at me seriously.

I nodded, "Very serious."

"Ow!" The girl in her arms put a headbutt on my heart and complained to me, "It's all a lie, you big liar, I don't trust you anymore."

I raised my hand and pressed the back of my sister's head to prevent her from bumping around.

"What did I lie to you about?"

"You lied to me that you love me, but you don't love me at all." My sister pouted, her warm breath on my chest.

My sister's answer left me at a loss. We were talking about running and exercising. Why did she bring up the question of whether I love her or not?

"I don't know what you're saying, we're talking about exercising now."

"Yes," my sister raised her little face and looked at me seriously, "If you really loved me, you wouldn't force me to run. You forced me to run, so you don't love me."

I……

This logic, oh my god.

"How did you come to such a conclusion?"

"The set and event in probability theory," my sister looked at me with a proud face, "assuming event A is that you really love me, event B is that you won't force me to run, non-A means you don't love me, non- B means you're going to force me to run, so event A equals event B, and non-B equals non-A."

After she finished speaking, she looked up at me with her head up and smiling, with a very witty expression on her face.

I knocked on her forehead speechlessly, "You, don't be ashamed. If your high school math teacher heard what you said, I'd have to scold you for being bloody."

My sister is not happy anymore, she stared at me angrily with her big bright eyes,

"A=B, non-A naturally equals non-B, am I wrong?"

Seeing the dissatisfied expression on my sister's face, okay, I will temporarily turn on the Xueba mode, so that she can honestly go for a run with me tonight.

"I still use your knowledge about sets and events in probability theory to refute you," I gently stroked my sister's hair on her back, "Listen... Let's say set A means I love you, as A complete collection of all events, are you okay with it?"

The sister shook her head, expressing no objection.

I continued, "Set B means I won't force you to run, then as you said, I love you will not force you to run, so set B is included in set A, no problem."

"No, why is B contained in A instead of B containing A?" My sister scratched her head and looked at me with a small face. "You don't force me to run, it proves that you love me?"

"Idiot, in addition to not forcing you to run, I love you, and there are many other things that follow you," I gently tapped the tip of her fair little nose, "Understood?"

My sister smiled and opened her mouth to bite my finger, but she didn't bite, so she looked at me with a small mouth, "Understood, you can continue."

Looking at the cute little appearance of my sister in my arms, I no longer have the idea of ​​using pure mathematical theory to convince her.

Whether the logic is strict or not is no longer important at this moment. Whether it is a sufficient and necessary condition or a sufficient and non-essential condition, for us, event A is the absolute and only truth.

Seeing that I kept staring at her and smiling, my sister happily pushed me with her little hand on my chest, "Speak quickly, you haven't finished yet."

I smiled slightly,

"In the Venn diagram, the circle of A wraps the circle of B, A is the complete set, and the non-B is naturally in the A set, even if the non-B is not in the A set, then there is the event that I will always follow you. C, event D, and event EF after that."

The elder sister tilted her head, obviously not quite understanding.

I gently stroked her warm jade back, took a deep breath of the fragrance of her hair,

"I have one thing that doesn't go with you, but there are ninety-nine other things that follow you. I have one thing that wrongly proves that I don't love you, but there are ninety-nine things that correctly show that I still love you. you."

My sister opened her mouth and bit the clothes on my chest, "I don't know why!"

"Does this have anything to do with not knowing Li?" I couldn't help laughing. "It's your own stupidity."

My sister pinched my chest gently, "Oh, don't say I'm stupid, I'm a witty little fairy!"

After speaking, she suddenly looked up at me,

"By the way, brother, you haven't had lunch yet."

Hearing her mention this, I realized that I haven't eaten yet, but I don't feel hungry either.

So I shook my head,

"Not hungry."

"No!" My sister left my embrace and looked at me with a serious face, "No matter if you are hungry or not, you have to eat, or you will get stomach problems in the future."

Saying that, she grabbed my arm with both hands, dragged me,

"Come on, I'll invite you to the cafeteria for dinner."

What she said really made me laugh bitterly. I invited her to eat steak, and she invited me to the cafeteria! By the way, thinking of steak, it seems that my sister really wants to go to the steak shop on the top floor of the shopping center.

I stopped, and my sister who was dragging my arm saw that she couldn't move, so she turned her head and looked at me with a puzzled face,

"Why don't you leave?"

"Didn't you always want to eat steak last night, I'll take you there now."

"Now?" My sister was slightly surprised, and then a flash of excitement flashed in her eyes, but then she felt helplessly on her belly, "No way, I finished my class this morning and ate with Qianqian and the others. It's lunch."

"Eat it and eat it as a snack."

"No!" My sister shook her head firmly, "It's a waste of snacks. We'll go in the evening on Saturday. I'll eat less during the day, so that I can eat a lot at night."

I raised my hand and tapped her smooth forehead, just smiled and didn't speak.
