I'm actually pretty good at assuming the best, but I still don't feel comfy when Michael is far away, until I either get a call, or an email from him.
Today he is in Yerevan, the capital of Armenia. This is his 3rd or 4th trip; he has colleagues there, and one of his grad student advisees (Armen!) came to the US after Michael met him in Yerevan. Our family loves Armen, who has travelled with Michael to Italy (tough job), Toronto (in the winter) and will be with him in Barcelona, Spain.
