Sexy Mexy

I'm in Playa del Carmen since yesterday. It's nice because my family and aunt are staying at a beautiful fancy resort--I've never ever been to a place as nice as this--and Pat and I are staying in town at a little hotel where there are shops all around and live music at night that's nice to fall asleep to. We made a little cat friend. What does it mean when cats have a little piece of one ear clipped off? Is it that they've been part of an experiment or something? I forget.
