Wow thats really creepy O_O I hope you drove home or something, i usually bus home from the gym and i would have been totally paranoid the whole time
My funny story involves cycling. I did a stationary cycle class (spinning class?) and all the bikes are pretty thin so you can pack quite a few into the room. Anyway, it was a really good work out and at the end I went to get off my bike. I accidentally got my right foot tangled in the peddles and being a bit shakey i tripped, feel forwards, and smashed my shin into the stationary bike in front of me xD So you can imagine me lying there on the floor, one foot tangled up in my bike, arms flailed trying to grab something
It's funny looking back but i was pretty embarassed at the time
