Sorry, your friend clicked the wrong email addy, that was supposed to go out to everyone else on the email list. It's a surprise party for you. Actually more of a drug intervention. We figure you're on drugs for asking a bunch of strangers why your friend would send you that email.
Had you been sober, you would have just asked your friend what the email was about. So that cryptic email also served as a test. Which you failed btw.
