The other day I saw a guy on the train looking at pictures he was actively receiving of a topless woman. He was clearly enjoying it, in his own little world, so I leaned over and said “don’t get scammed buddy”.
His anger brewed for a few minutes and he decided he wanted to fight me, so he menacingly stood up. I remained seated and told him to sit down. He ended up grabbing me by the throat, while no-one around did a thing to stop him.
It’s made me think twice about interacting with random people, tits or no tits. But I doubt I’ll learn anything from it and continue with reckless abandon, because life is mundane otherwise.
Involving yourself by commenting on very personal matters, especially in a smug or condescending manner, is almost guaranteed to end badly.
This is quite entertaining and I'm glad there are people like you, but you didn't even think it would be inappropriate to comment on a naked picture that someone receives in a private conversation? I don't even think you were supposed to look at his phone.
