By the window

Twelve

For the past days, there were no signs of him. I once went to the soccer practice to watch with my friends (acquaintance). He was not there too.

Makes me want to ask his close friends. But I can't. First, I don't know who to ask. I usually see him alone. I also just usually see him on the same window staring blankly at nothing. His stares are always so far away.

Another thing, we don't really know each other.
Sure, we talked, but that was just one time.

It'll be weird for people if I ask about where he is all of a sudden.

Why am I even worried about him?
