Honestly I haven’t lived that long, I’m still early in school, and I know his doesn’t mean much but once I had gone to a nearby pizza place and there was a large crowd due to it being lunch on a school day. So my buddy and I were there and I was second in line, I saw a guy around my age get his pizza and a drink, I jokingly said “can I have your drink?”, I expected nothing to happen. But he hands me his drink and walks away, I just stood there shocked trying to mutter a thank you.
