Maybe this was just a good turn. I was talking with a retired colleague yesterday and mentioned another retired colleague. He said that person for some reason doesn't want to communicate with him because he had written an email to her and never got a response.
Man, that just didn't sound like her, so just now I wrote her and told her this. I said about three times, if this is the case, no problem, no explanation necessary, not my business, thinking maybe there was some spat I didn't know about, but in case it's a misunderstanding, here's his email address.
She replied almost instantly and said:
Good heavens! I don't remember getting an e-mail from him and I just checked and can't find anything.
And then went on to say she is going to write him right now. So that's nice. I've healed one little molecule of the world.
