my problem

I have a problem/obsession. Marcus likes to trade his pokemon cards on the bus. Personally, I feel like he gets taken to the cleaners sometimes, because he's given away some neat cards (did I just write that?) for some not so cool ones (I know). Today Marcus came home with new cards, Star Wars cards. He traded all his pokemon cards (and he had about 10) for some stars wars cards (like 4 cards!) I'm trying to be supportive. I know that Marcus just likes trading cards and doesn't care how many he has of what type. I just know that some other kid cleaned up today! So, I'm going to try and relax about this and just hope that Marcus enjoys what he has.
