WTF? One of my best real life friends was supposed to be at my place between 6:30-7:00 to drive me to my birthday party so I can drink. (Though, she already flaked out on driving me HOME, because she's leaving early??? So I had to get a ride with someone else.) 7:30 rolls around and I finally call her and she goes, 'oh, I was gross and needed to shower and change. I haven't even left yet.' Alajhdjhjhjasdjdhfj.
Last thing a friend did that let you down/pissed you off?
