I was sitting on a stoop waiting on a friend, as the Stones used to sing, when I sneezed very emphatically, as is my wont. A little boy emerging from the elementary school across the street cried out in a high, triumphant voice, “Gesundheit!” Not to be outdone, all the other kids joined in, and for a second the honking cars of the early evening were drowned out by a symphony of children’s voices blessing me. The cockles of my cold heart are officially warmed.
