Don’t be one of those people hugging the very edge of the subway plateau with a thousand people behind you. I saw clips of that and it looks dangerous as hell.
So I was at a St. Patties Day Parade once. And these two chicks started fighting. Pulling hair and stuff. A circle firmed instantly. I was young and stupid and I stepped in. Tried to talk some sence into them... Anyway, one of them had an admirer with a half empty 40 who came at me. I had the composure to diffuse the situation and fade into the crowd. Not sure how the fight ended, I was drinking too. Definitely stay safe out there
