When I was around 22. I was taking a jeepney ride in Olongapo City, Phillipines
It was in the afternoon and I was the only passenger until a local jumped in. It wasn't my first trip to the PI. He asked if he could see my wallet, or something like that. Being young, smug and and full of.. confidence. I pulled it out handed it to him. I saw the smile on his face as he figured he'd just scored. He told me how nice a wallet it was and I saw his eyes darting, looking for a place to jump out of the jeepney and steal my wallet. Then he opened it. Not a peso in it, no ID, nothing but an empty wallet. He handed it back to me and got off the jeepney at the next corner.
I may be dumb but I aint stupid.. (I need to post that one on the annoying things people say thread)
