What's wrong with people?

Last night my purse was taken while we were at our yoga class. I left it in my locker (unlocked) I know, I know but it's a fixed number of people there, not a general public kind of place and we all do that. It was under my coat as always. It was so upsetting. It was "found" later but whoever had it had rifled through my wallet and had taken all the gift cards/reward things from stores that I had. Wedding presents and such. Thankfully that was all, my credit cards were all there (even though we cancelled them anyway for safety) and my license and brand-new-hadn't-even-set-up-voicemail-yet-and-quite-expensive cell phone. so it could have been so much worse. As crappy as it is that all stuff is gone ($400ish worth of stuff) I feel worse for the owner. It's SUCH a small place, it's personal training by appointment so to think one of her clients or trainers is a thief is awful. Alex and I have our suspicions on one person who was acting weird... I'll probably talk to the owner about that later.
