Question: Do you expect everyone you recognize; have had a good time with at one point in time; to stop and shoot the shit whenever you run into them?
Honestly, I run into friends all the time at malls. Some that I don't see for weeks on end. 95% of the time, that's all it is. "Hey Dude" and a "Hey" back.
Especially if they are with someone else. I do not expect everyone I see with their friends/family to stop and talk. If I had to stop and talk for 2-5 mins each time, I'd never get to where I was going and doing what I need to on time.
Get over yourself dude. She acknowledged you and didn't have time to talk. She said "Hi" FFS.
Oh, and Artie Lange has something to say on this:
Waaaaaaaaaaaaaahhhhhhhhhhh Zoe wouldn't stop to talk to me wwwwwwaaaaaaaahhhhhhhhhhhh!!
Seriously, I don't know you, but you've come across as the biggest douche of the weekend. Congrats

I'm sure this will make BROmasters.
