The first thing that comes to mind is one time when I was pretty drunk, in my late teens, hurt my legs trying a very ambitious(stupid) jump and then passed out at a bus stop. Woke up later, no phone battery, in the city about an hour away from home and nobody else I knew around.

Limped into a 24hr kiosk and asked to borrow their phone to call for a ride. Got a no. Tried explaining the situation, no sympathy.

A guy who happened to be in there saw that I was really not having a great time, came over and just hugged me and said it was gonna be alright and let me use his phone. No idea who you are, wouldn't recognize you if I ever met you again, but thanks for that.
