Never too late to say thanks properly

When I became engaged, the women of my religious institution (my mother's contemporaries) held a shower for me, for which I immediately wrote thank-you notes for the luncheon and the gifts.My husband and I were married by a judge but had a reception several months later in my hometown. While I was mingling with the guests, one of the ladies who had attended the luncheon came up to me and told me, with a smile, that I had written her a thank-you note for the wrong gift (I got you X, and you thanked me for Y) and that she thought I would like to know. I was mortified, of course. I apologized effusively, said it must have been new-bride idiocy, thanked her for the gift she did give me and retired red-faced.It has haunted me since then, and I've never seen her afterward without feeling like a fool — and I've been married 29 years.Should I have written her another thank-you note? What would have been the best response? Since no one else mentioned anything, I can only hope that the rest of the notes were accurate. It's years too late, of course, but I'd love to lay this ghost to rest and feel I acted correctly at the time. Personalised Thank You Gifts - Make Your Thank You a Golden One.Twenty-nine years is a long time to feel like a fool, and Miss Manners would like to offer you some relief. But alas, she cannot bring herself to declare that the fact that the lady already had a (misguided) letter from you, or your including thanks with your embarrassed apology, took the place of a genuine and correct letter of thanks.Presumably the lady herself has long since forgotten. But you have not, which does you credit. So the job now is to get it off your conscience.
