Don't be such a tight a$$ with the "unsolicited" canard. It's not like it took up more than two seconds of your time. You've already invested more than that bitchin' about it.
firebrand is throwing a party and invited you. See it for that and nothing else.
A simple "please remove me from your ping list" would have been the gracious way of handling it.
Looks like there will be a number of speakers you might want to come hear speak and perhaps meet. The invite still stands if you change your mind. If you need assistance getting there, we may even be able to help with that.
I'm busy talkin' to this guy
When I see outta the corner of my eye...
Look who's here, how you doin'.
Why don't you tell me who let you in?
We don't care if you think our party's cool
'Cause we do!
And we don't care if you had more fun in Sunday School
'Cause who invited you? Who invited you?
