I can't throw it away!

Strangely enough, I was just going to do the same to my room. I have to clean it out and decide what I want to take to university in a month. I have all my notes saved from grade twelve sciences, old drawings, model cars, pokemon cards, a binder full of hockey cards and old elementary school projects. I want to throw most of it away, but my mom wants to keep it for sentimental value.
I think the hardest thing to throw out are some t-shirts I have from a music camp I went to. I have about 4 of them, and it was a big part of my life for a long time. I just can't see myself throwing them out. They may have to spend a few more years in my closet.

Jam it back in, in the dark.
