Can I?

An email I really want to send:

Dear E,

I find it detrimental to our friendship when you tell me stories about having the opportunity to fuck my dear friend’s little sister but deciding not to in deference to your new girlfriend. It was not the best way to bring up the topic. I am not KE (his roommate), after all.

At any rate, I do sincerely hope for your happiness, and for your completely lost common sense to return to you. See you at the Christmas party!
