I guess I’m old

So yesterday I tried to get to the bottom of this Pokémon craze by going straight to the source: my little cousins. Ages 7 and 9, I asked them to explain what was so cool about Pokémon to me. They looked a little confused, and they showed me their cards, but they couldn't really explain what was so good about it. Oh well…I guess there's just some stuff that "adults" can't understand.
