Dear Amy: Several years ago, my daughter had a preschool teacher she loved who was fired for, what seemed at the time, a dubious reason. I related to her predicament, and I met up with her a couple of times in the immediate aftermath so that my daughter could see her and to talk about the situation. I did not expect to develop a long-term friendship with her. Since that time, she has contacted me sporadically, whenever she finds herself in a difficult emotional situation. We are not friends, and she only contacts me when she’s having an emergency.
