A few years ago at a city festival, me and two of my friends were sitting on a bench in a park, when a group of about 10 guys passed us and saw our booze, so they wanted some. At first I refused, but eventually my friends gave 'em some in order to avoid further problems. We left the park but returned there a few hours later. My pals were sitting on the bench again, and I was standing in front of them, complaining about how they didn't have the balls to resist some "lowlife scumbags". I went on a tirade, and then noticed their grim expressions. I looked behind me, and one of the scumbags was standing there. He immediately called all of his friends, who surrounded me and gave me some punches in my face.
If you think you only see stuff like that in movies, take another guess...
Another one: last year, also at a festival (a normal one, not in a city), I had the biggest crush I've ever had on a female friend of ours. I still kinda have btw, but back then she didn't know it yet. I had this masterplan to get her to her know I was crazy for her. Anyway, I've always been the photographer of our gang, so as usual I was taking pictures, including lots of her, sometimes when she wasn't aware of it. Then at a moment when we were all lying on the grass, my best pal was looking at the pictures on my machine, and suddenly he went "half of these pictures have <crush> on them!". That's when she found out. So much for my masterplan.
