To be very disappointed in my brother...

[Treacletartfortea]

because he didn't phone or send a card to my DH for his 60th birthday at the weekend?
Brother is 50, unmarried, never had a long relationship in his life, but he did know about the birthday and the plans for it- just us and DCs to nice restaurant.
We've been married 30 years so it's hardly as if my brother doesn't know him or anything. He lives 300 miles away so I thought this once he might make an effort. (He never does anything for the DCs birthdays either even though they are his only niece and nephew.)

YANBU and I'm not surprised you're disappointed, but some people are not so good at things like sending cards, etc. It doesn't mean he thinks less of your DH.
If he's OK/ considerate in other ways don't sweat it too much. and resist temptation to send sniffy text/ email

ok well maybe not a card, but a phone call on the day or the day before perhaps to wish him a nice day and a good celebration?

Hmmm by dh would never think of sending a card either. Think my dad did it once and we nearly all had a heart attack. My mum was in hospital at the time and he sent his niece a 21 birthday card. I wouldn't even think about it tbh

YANBU, but some people are more invested in occasions than others.

It probably slipped his mind, if there weren't any plans that involved him. I'm crap at remembering birthdays. It doesn't make me a bad person, they're just not very important to me, mine included. I do try to remember children's birthdays though, because they're truly exciting and important to them.

300 miles away? I wouldn't expect anything from him, unless they were very good friends in touch with each other in their own right.

YABU. My dh never buys a card for anyone except me. That includes his parents and siblings. I never get the fuss with cards.

It's different expectations f different people, but if he doesn't usually send one, then I don't understand why you are surprised or disappointed that he didn't this year - I'd expect that to continue.

YABU.
He lives 300 miles away.
Why should he phone or buy a card for your DH?
If you were that concerned with an acknowledgement from your DB then you could have invited him to the 'nice restaurant'.
BTW, men hardly ever buy each other cards. Didn't you know?

Yanbu. A phone call costs nothing and after 30 years that's the least he could do.
But As you say, he has never bothered about his only niece and nephew so I think this shouldn't come as a surprise. It's still unkind though.
