It's a tie between unprotected sex with a stranger I met at a bar, and sleeping on a bench behind the train station in Barcelona.
Luckily, getting robbed behind the train station was the more serious consequence of my poor life choices.
I was actually approached by a hooker there.
After I told her I only had 10€, she said that's OK.
Luckily in that moment, my big head did the thinking.
