Just had a great call with a vendor--specifically, a coordinator and a tech sales person. I asked a bunch of questions, the TS person clarified most and filed the rest as tickets, all went well. I got to be myself, and only slipped and swore once. "My dad was a systems engineer. I learned how to swear at the knee!"

At the end of the call:

Coordinator: Thank you so much, and feel free to drop us a line any time something crosses your mind...
TS Person: *sees where this is going; starts cracking up*
Me: Yall done opened the door to the vampire!
All: *crack up*
