What is this feeling? WHy do I care?

Plot:

Over the weekend, I've been thinking; I know Quincy is an only child, and it's how our charactristics are made. Today at lunch (in the library), at the right moment I asked, "Hey Quincy, are you an only child?" He took 5 seconds to think, then slowly shook his head. "I have like a 11 month old brother." he replied. Somehow I don't know how much it's effecting me all day, or even why it's effecting me. But I was wrong, he's a big brother now....

Whenever Monica was talking to me, I was thinking about it instead of listenig into her. In P.E., while everyone else was doing their jump rope test and we finished, I sat there thinking about it. "WHy do I care about such little things? So what if he has a brother, how does it affect me?" I thought over many times. Many theories came up, but I only found one true answer.

Emotions: It states your feeling mood and expressions. "Love," I thought about it. It couldn't possibly be an emotion, but when I went in circles, it came. It DOES give feeling about others, it DOES give a mood, and it DOES express who you are. But what I realised is that love/heart/care is the most important, and the strongest emotion you can fight against.

My speech was about emotions, how they are made, and how they affect our life today. I can't believe I didn't realise the most important emotion of all until now. Still, I can't find why I'm so..so...protective about it. There's nothing to protect. I just don't know what my mind is doing.

ONe reason could be because i didn't expect it. You know, Quincy's all..a "bully" and so, it's sorta obvious that he was an only child. An only child experiences the lonesome and can't feel or fit in with everyone else. When you want someone to talk to, there's no one there but yourself.

Next is probably Quincy himself. Like in episode 7, "Island of Misfit Boys" of DIgimon Frontier, Takuya takes care of Tommy like his little brother. Koji doesn't understand cause he doesn't have any sibilings.
"Pretend Tommy's your brother. Pretend that you would be the one to keep him away from danger and all the sad things happening around him." Takuya said, making Koji realised. Quincy seems so independent, and it just feels so strange to think that now he has a brother, someone to talk to and play with. Someone that you now have to take care of, and will always be your friend. And now, Quincy has to be more responsible.

But just having a brother when you're in 6th grade sound crazy. I mean, when you're in college, your bro is at like 3rd grade. And like while your'e getting married (not going over, but still), you're bro's still in high school! Cousin sound more like it.

Now I understand. Quincy probably rides his bike to school because his parents dont' have time to pick him up or drive him. Sometimes when it rains, he dosen't ride his bike. You see his parents picking him up 20 mins after school ends. He gets less attention, and it just affects your emotions too. Except, I haven't realised it or seen it in all of the 11 months.

How he said it, thought of it, it just runs in my mind. I can't get it out! I just asked like a normal person would ask to a friend: nice and soft, maybe too soft. Someone who's used to it would quickly answer a yes or no. But Quincy looked down and took a while to think. Was he not planning to tell me, or didn't want to have a brother?

I don't know why, I can't get it out, I don't understand! I don't even know why I care about such little topic and little words! But really, know many times do you experience a crush how you never knew had a sibiling. I don't know what's becoming of me. I feel so different, of something I don't know...I can't get it out. Whe n Iread, it's still stuck. Doing hw: same. Went to my piano lessons today, went day dreaming!

How do I get out of this? I don't know waht to do? I'm as comfused as BlackWarGreymon, trying to find my heart. Please, advise, anything, a comment, a suggestion, help me get it out!
