Dear Amy: My in-laws always seem to feel the need to comment on people’s weight, either right to their faces at a family function or gossiping about it behind their backs. Ironically, they are not exactly thin. My brother-in-law and his wife are quite heavy (my brother-in-law much more so), but his parents (my in-laws) only comment about his wife, exaggerating her weight over his. My mother-in-law has said to my daughter, in front of everyone at Thanksgiving, ‘”You were pretty heavy there for a while, but you look pretty good now.” My daughter is the recipient of at least one insult per visit.
