"Dear Miss Manners: When my husband and I were married a month and a half ago, we received congratulatory cards and gifts from virtually all friends and family, except his parents. I feel awkward even writing about this, but it seems a little odd not to receive a wedding present from his parents. They hosted a rehearsal dinner at their home, so perhaps that was their wedding gift to us — we aren’t really sure. They are quite stable financially, so I honestly think that has nothing to do with it. I have talked to my husband about the situation, and he said he thought his mother wanted to wait until after the wedding to give us a gift that we did not get from other guests. Neither of us wants to say anything to them about it, lest it be assumed we are trolling for gifts. Still, my feelings are quite hurt that we did not even receive so much as a card from them. Do you have any suggestions for us?"
