This is kind of another reason why I stopped being a crazy collector that I was when I was younger. It was especially tiresome when we'd move all the time and I'd have to pack up my collections, unpack them, rearrange them, pack them up again, unpack them again, rearrange them again, etc.
Unfortunately, my mom's trying to get me back into that phase again: for the past two or three Christmases, she keeps getting me collectibles that I really don't want - I've gotten to a point where I've had to install shelves in my room just so I'll have somewhere to put them. I mean yeah, some of them are nice to look at, but what do I do with them? I just dust them each week, and that's about it.
I remember when I was a kid, I wished my favorite Cartoon Network shows had more merchandise because I wanted to fill my room with them: Courage, the Eds, it didn't matter, I just wanted more - it was part of being a fanboy. Now, as an adult, I feel "meh" about the whole thing, and kind of have that Oscarfan I don't care either way mentality about it all.
