He visits me while I am at our store. And we have an "arrangement" that if I say "this is not a good time," he leaves without question, because he respects that I am trying to conduct business.

He's highly intelligent and generally very interesting, and we have some nice talks, except when he starts pontificating about certain political points. And I suppose I do enjoy the challenge of trying to reach through his cognitive blind spots so he has to think outside his paradigm... although I don't often get very far with it.

Familiar with the saying "Too good to leave, too bad to stay?" It's a bit like that. Once the early summer and our "tourist season" begins, I'm unlikely to see him much...
