What am I to you?

Chapter 4

"Come in" I said as I opened the door to my house. I walked into the living room with Ryder following behind me. I set my bag on the couch and turned to look at Ryder.

"Would you like anything to drink or a snack?" I asked.

"You can choose whatever you want"

I nodded my head as I made my way to the kitchen. I cut up some fruit and grabbed two water bottles. While watching a Korean drama, I learned that eating snacks that don't contain sugar is good when you are studying.

I walked back into the living room with the bowl of fruit in one hand and the water bottles in the other. Ryder had a picture frame in his hands. From here I can tell it's the frame where I am with both of my parents and my brothers. I swallowed the lump that was beginning to form in my throat.

"My mom isn't going to be here until nine, so we have a lot of time to study"

His eyes snapped to mine and set the picture frame down.

"We should go up to my room. I have a board in there that we can use"

Ryder walked over to the couch and grabbed my bag. I began to make my way up to my room.

Wait a minute. Did I clean my room? Oh gosh! I hope that it is clean for my sake. If my room is dirty Ryder might just end up making fun of me.

"I'm sorry if I have a mess in my room" I apologized in advanced. I opened the door and Let out a sigh of relief as I noticed my room was clean. I set down the snacks on my desk and walked over to my bed.

"You know, if you have sex in your room and you don't want your parents to find out, you might want to throw away the condom wrapper"

My eyes widened at Ryder's words. I walked over to where he was and noticed the little wrapper next to my night stand.

"I didn't have sex I swear! I was just curious to see what condoms looked like but I didn't even use it! I'm a virgin I swear!" I blurted out as if my mom was the one who had caught me.

Ryder began to burst out in laughter. My cheeks turned a shade of pink at the embarrassment. I brought my hands up to my face to hide myself from Ryder. I peeked through my fingers and enjoyed the sight in front of me. Ryder's head was bent backwards. His eyes were closed. The sound of his laughter made me feel butterflies in the pit of my stomach. I scowled at the realization.

"Okay that's enough let's get to Calculus"

Ryder's laugh seemed to disappear as he groaned. I took out a board and placed it on a chair. I took out some markers and my notebook from my bag.

"Okay, what exactly did you not understand from today's lesson?" I asked.

He took my notebook from my hands and studied it. I tried not to stare as a small scowl formed on his face. He bit his bottom lip in concentration. I really wanted to tell him to stop doing that but decided against it.

"I understand how to take the basic derivatives but I don't know how to do the trigonometric ones"

I took my notebook from his hands and wrote down some of the rules.

"Okay, there are a couple of things that you have to remember in order to accomplish those. The derivative for sine will always be cosine. The derivative of cosine will always be negative sine..." I watched him concentrate as I explained to him the math problems. He was biting his lips again. I was certain I was going to walk to him and stop him from doing so, until he spoke.

"How do you know that they will always equal that?"

"That is a good question. They are actually proven by using the equation for limits. Derivatives are basically a short cut for finding the limit of an equation"
