Dear Handsome Coworker,
The other night was a nice change and I was looking forward to a lot of heavy petting and kissing. Instead you threw up on me. I mean WTF??? Can you not handle your drinks? I was highly disappointed and I expect you to make this up to me in a huge way. When I say huge I mean fantastic mind blowing sex. You have one more chance to get this right.
Can't wait to see you tomorrow!
