About the time of the explosions in Boston I was on the phone with a colleague there who had been visiting family and was at Logan on the way back. Neither of us learned about the attack until later. Fortunately none of his family was harmed, though some were at Fenway, close enough to hear the blasts.
I have nothing useful to say, but it seems I ought to write something, if only to express sympathy for the victims and their friends and families, and even then I don't know what to say. We all feel pretty much the same way about this, I suspect, varying only in the relative degrees of sorrow and anger and bafflement that anyone could be enough of an asshole and coward as to do something like this.
