I called our answering service and was connected to "Jay", one of our clients who was constantly in conflict with his sister. Upset with her about something, Jay proceeded to make threats against his sister. Of course, I had to take these seriously. I tried to get Jay to tell me where he was, so that I could get someone out to check on him and pick him up if necessary.
Jay knew the drill. If someone came out and believed that Jay was a serious danger to his sister at that point, he would spend Christmas in jail or the local psychiatric facility. Instead of telling me where he was, he asked me if I thought he was crazy. His sign off was "Fuck you bitch!" Then, perhaps thinking that greeting was a bit harsh, he added "And Merry Christmas!"
After hanging up, I immediately called the sheriff's office. They were able to pick Jay up, calm him down, and take him safely home.
I have not seen this man in years, but I still crack up when I remember his Christmas greeting. Merry Christmas, Jay. Wherever you are.
