Some kids collect video games, others collect dolls, or Legos, or board games. I collect something different. I collect key chains. I've got 52.
Whenever I travel to different places, I get a souvenir from a shop. For example, when I went to Puerto Rico, I got a key chain as a souvenir.
Collecting key chains looks easy, but it is a little hard. You have to make sure you want it, and be sure you don't have it already. When I choose key chains, I tune out everything else. I concentrate on the choices.
In my room, I have a key chain tree that holds them all. They are great memories of all the places I have been. I also like getting them as gifts.
