Dear Coworker,

I'm sort of attracted to you, and you sent me a text on Friday after happy hour saying we should hang out again with fewer people. However... 1) You work with my dad routinely. That's just a problem. 2) You and I met through the Unattainable Coworker, and I'm definitely not over him. 3) I can't tell, but I suspect you have the potential to be slightly douchey. After all, you're a tall, successful, good-looking, fairly interesting individual. You aren't over 30 and single because you lack options. 4) Did I mention that you routinely work with my father??

Oh well, thanks anyway for the drinks on Friday and the attention.
R
