My mother actually raised me to think they weren’t necessary under most circumstances.
I write them far more often than I was trained to write them (and I don’t write them nearly as often as I SHOULD - I’m sort of random in my thank you notes). I’ll write them for visits and dinners and parties (occationally and randomly) and completely miss them for gifts sent through the mail (when you SHOULD write them if for nothing else than to let the sender know they arrived).
I agree; there is no controversy here. If you weren’t raised in a culture where you send thank-you notes for all gifts, then you don’t send them and no one thinks a thing of it. No controversy at all.
Um, as long as you’re still in that culture, of course. If you’re still not sending thank-you notes for gifts when you’re in a different culture where thank-you notes are customary, it’s probably mistaken to believe that “no one thinks a thing of it”. A lot of people will think of it, and what they’ll think won’t be flattering.
You make a good point. Of course, they are not done when gifts are exchanged or when the gifts are trifling (like the “gag gifts” at an “over-the-hill” or batchelor party).
Unless my gift was particulary lavish*, I do not expect a note if you open it in front of me and say “thanks” then. But since wedding gifts are usually opened after, then the note is a must-do, if nothing else to confirm the expected recipient got it.
*(If I have given you a new car, then hell yes, I expect a personally hand-caligraphied and Illuminated note on real parchment- or a blow job. )
I can’t speak for all of Canada, of course (they still won’t let me), but in my 40 years living in Western Canada, we don’t send thank-you notes for any gifts but wedding gifts. I have never received or expected a thank-you note for any gift other than a wedding gift, and I have never sent one for any gift other than a wedding gift. Eastern Canada may be different, but I’m not moving there, either.
