Are wedding anniversaries personal?

[DuchyCazalet]

Do you acknowledge anyone else's wedding anniversary? Would you note the date of the wedding anniversary of your son/daughter and send them a message to wish them a happy anniversary?
MIL always sends us a message on our anniversary but my parents never acknowledge it.

My divorced parents both send cards. Pretty sure MIL has no idea when ours is. My bessie, who was also MOH sends a card but that's it. I dont really expect anyone to mark it but us. Its nice my parents do but I'm not mad MIL doesnt.

My mum sends a card and seems to expect me to send them a card every year for their anniversary. I have done for milestone ones (e.g. Ruby) but otherwise I can't be bothered with it because I don't feel like they're a massive deal and I wouldn't mind if no-one sent us cards etc.

My mum remembers, but it’s on her birthday!

People sent cards on our first anniversary, but can’t remember any since then.

People tend to say happy anniversary if someone posts something on Facebook about it being their anniversary. But generally speaking I think it’s a personal thing for the married couple.

I remember siblings and mum and dads and send a card and sibling gets a present for whatever year it is ie cotton / tin etc . My PIL have never once even wished us happy anniversary or sent a card - pisses me off every year 😂

My PILs used to send a card, but no more. My parents have never.

I personally wouldn't send a card to my kids as I find cards a bit pointless, but I would offer to babysit.
