2X2Many - There is no way to know which h is coming for the visit. Any, who knows, you may even see various personalities make a cameo! My advice is, don't focus on it because you have no control over this piece anyway. If you are expecting him to bring up the r, he'll probably be coming to discuss his newest favorite flavor of potato chips. MLC is just not predictable, at least not over here!!!
It sounds like you are well prepared on various issues, should h raise those. I think that's the best you can do.
As for a pep talk-you DEFINITELY have this! You are a well tempered and patient person! If any surprise conversations are raised, just remember, silence is a good, near and dear friend to you. This way, you can step away and process later.
Last bit of advice: try to do something to reduce anxiety!!
Thinking of you . . .
