By not wanting to call people on my birthday?

[FantabulousFryingPan]

Apparently it is the height of bad manners not to call my on my birthday to thank them for the £10 cheque they put in my card. I don't spontaneously call them at any other time so I find it a bit odd as to why that is expected.
Surely they should call me to say happy birthday at which point I thank them for the cheque. Or AIBU? And yes, I do know how trivial this is!

Call me, not my.

Rude, discourteous, lack of breeding and manners to not to thank anyone for a present.

Who's "they"? That's kind of the point IMO

"They" who?

I used to have this every year. My nan used to insist I rang her on my birthday, to say thank you. I got annoyed every year, til I was in my 30s and my nan died. Now I wish I'd just phoned her more. (Not sure what I'm trying to say to you though!)

My gran/aunt/etc always expect this.
I have 2 kids and am usually out enjoying myself on mybirthday
I call a few days after or write
And I get "oh we didn't hear from purple on her birthday. We didn't know if the £5 had arrived and we were worried"
I don't expect them to call me on their birthdays!!

Actually yes, it is really rude to not thank someone for a gift. No matter how big or small it is.

You should thank them for the presents but you can do that with a note, or call them on another day.

I wouldn't sit down with a list of people to call on my birthday. It's my birthday

'They' are the in laws. By the way I am
happy to call them the next day but don't see why I should have to put myself through an awkward phone call on my birthday itself.

Presumably it wouldn't take more than 2 minutes to thank them and talk about the weather or what you're doing for your birthday.
Boring? Yes but part of being an adult!

Text them. That way they still get the thank you and you don't have to talk to them.

In my family, it's everyone else that has to phone me on my birthday, to sing 'Happy Birthday' to me. After which, while they are still on the phone, I will thank them for their card / money / gift. Otherwise, they can wait until I'm ready.
Of course it would be rude not to thank them at all but that is not what the OP is asking.

YANBU. You must say thank you, next day or write to them but I do not see why you have to call them on the day. It's your birthday!

It only takes a minute or two make the call and say 'thank you'. They spent time organising getting it to you so surely it doesn't hurt to ring them and say thanks?
