I think it's a very good thing that you pre-warned him, Bunny. I have startled the heck out of a couple of friends that I hadn't seen in awhile - they commented that I seemed to be a bit stiff and I blind-sided them by blurting out that I had PD. One said "no, you don't" and then spent the rest of the holiday apologizing. The other tried to talk around it the whole time we were together. Not comfortable, and I've learned my lesson. Easier for people to find out what you're like in writing or over the phone, and then they don't have to feel bad about their reaction.

Hope you have a wonderful visit, it sounds like a very special friendship.
