There is a man in prison I’ve been writing to for some years. I write on plain paper, address an ordinary envelope, affix a stamp and a return address label. I get labels free in the mail with solicitations. My friend asked if I would order him return address labels like mine. I did so but he did not use them when he wrote to me. Why was this so? It took a few letters for me to appreciate the problem. He wanted his labels to be exactly like mine, with “Mr.” printed before his name. My error! I reordered.
