Thanks for the videos. He just tells people (whether Costa or X or anyone else) where to wait for him while he signs autographs. Nothing that I find unusual: they're not gonna just stand in front of the crowd waiting for him to be done. It would be awkward. No the one thing that always strikes me is that I find his way toward her a little cold, don't get me wrong, very considerate and gentle but somewhat distant and dismissive at the same time. I could be projecting though or it could just be his usual manner, I don't know if anyone else feels the same about the way they interact. Meg good luck with everything, there's always a huge need for math teachers!
