I fell off the bus.
Most passenger busses in Cuba are these trailers called "camels" for their shape. They are pulled by those freight truck rig thingys.
I tried to get on one but the doors shut on me. Those doors shut so violently, that I was thrown backwards to the ground. I was unharmed. The interesting thing for me was that people seemed concerned, not enough to come over and help me or ask if I was okay, but I've been in counties where people would laugh at that kind of misfortune.
