DEAR MISS MANNERS: I always sent a Mother's Day card to my dear mother, who has since passed away. I also acknowledged any close motherly relatives.
My three children are grown with children of their own. However, my one daughter seems to think that I should give her a card, whereas I think her own children should have that filial duty when they are old enough to understand. (I am also of the opinion that the greeting card industry encourages extra card-sending for its own benefit.)
GENTLE READER: It was Miss Manners' own dear mother who declared Mother's Day to be a mistaken notion. "It implies that there are 364 days on which children do not have to show their love and appreciation for their mothers," she would say.
Yet she also taught kindness, which makes it difficult to oppose the spread of Mother's Day beyond mothers and mother-figures. But yes: It seems ridiculous and self-centered for a child to demand such acknowledgment from her mother.
Perhaps you can find a gentle way to point out that your daughter is going in the wrong direction: "You're not my mother, dear; I'm yours."
