To expect a thank you for wedding gift?

[TheMauveBeaker]

Younger family member got married in January this year, couple already lived together in their own house so ‘traditional’ wedding gifts weren’t required. If anyone wanted to give a gift, they requested cash towards a honeymoon to be taken later, All of my family members gave cash, in cards, which were collected at the reception. Nobody has received a thank you, written, verbal or digital.
Is it no longer a thing to send a thank you, whether it’s a text, a printed card or (highly unlikely) a handwritten note? I genuinely wondered whether it’s a generational thing?

YABU - nobody does that anymore
YANBU - the newly-weds should have sent/made some kind acknowledgment

It’s the same kind of people who don’t think friends or relatives buying their kids presents or babysitting for their kids is outdated because it’s the “village”.

However if said “village” tries to help correct their badly behaving child or even advise them on correcting their child they shut it down.

We wrote ours before the wedding!! It was recently, not in the 80s though 😁
We had a John Lewis gift-lift so could see in advance who’d bought what, so between us we wrote the lot. There was about 40 gifts, so we did 5-10 cards a night over a week. Then posted them when we got back from honeymoon.
