I met this dude at a house party like 15 years ago. I had no idea who he was, and had a normal conversation with him with small talk like 'what do you do for a living,' etc.
Apparently he didn't like that I didn't know who he was, and complained to the host (a mutual friend). lol fucking clown.
It's not just for the person you reply to, but also for anyone else who may come across this thread. That's how I see it anyway.
