Aibu to hold a wedding reception on sister's birthday?

[Sexolette]

I'll keep it short.

We recently had a tiny, family only wedding with the plan always being to have a party in the summer.

We are organising said party now and have juat sent out info to people to hold the date.

My sister has told me that obviously she is not coming as it's her birthday and why would she want to go to someone else's party on that day.

I haven't risen to the bait. Am I being unreasonable to hold the party on that date? ?

It's not a milestone birthday, mid twenties.

You could choose any day, why this one?

We want a midsummer Saturday, only have every other weekend free and have some other holidays booked in which mqke this the best date

Why your sisters birthday? There's 364 other days to choose. IMO YABU.

People don't own dates.

however I'm wondering if there is a history of sibling rivalry between you both

Given that you are waiting months and months to have this party, why choose your sister's birthday in the first place?

YABU and clearly goading your sister. You're also making it awkward for the rest of your family.

What a crap way to celebrate your marriage.

It's a bit odd that you chose that date tbh. I can't believe it's the only date available.

It sounds a bit insensitive, tbh. I've no time for adults who get terribly precious about their birthdays but for all that, did you not realise this this wasn't perhaps the best date?

Interesting interpretation Pinot.

As a family we never celebrate birthdays together

Didn't it occur to you to talk to her first about the date?

Seems a bit harsh of you to book this date when you have the whole summer to choose from. It might not be a milestone birthday, but I'm sure your sister will still want her own night out with her friends. Given there is ages to go, why don't you chose another day?

As a family we never celebrate birthdays together

It doesn't sound as if you'll be celebrating this one either!

Yeah, choosing that particular date was a shit thing to do.

It's not the only date, but as I have explained above it's the date which best suits us. I'm quite surprised by the responses to be honest.

YABU.

Whether you celebrate birthdays as a family or not isn't really relevant. You could have chose any number of dates but you chose one that you knew clashed with something. It does sound a bit inflammatory.

Exactly what Pinot said.

You are completely out of order. Pretty selfish thing to do and my first reaction was same as Pinot.

Are you the older or younger isiter? (nosey!)

Personally I dont see anything wrong with it - and this is another one where I cant make head nor tail of MN - most of the tiome the comments are along the lines of "no one over 6 has a party/bothers about birthdays/does it end in zero"

I still think there is sibling rivalry and if she doesnt want to come to your party, so be it.

YABU

That is going to be one awkward weekend

I am constantly amazed by the fuss that some adults make about their birthdays.
YANBU OP, your sister needs to grow up.

Mmm. Seems unnecessary IMO. You have months to chose a day and it just happens to be your sisters birthday. And the first she hears about it is a save the date card?

I am guessing not...

Older sister.

I was quite taken aback by her reaction. No rivalry, we're not that close.

Clearly everyone is a lot more precious about birthdays than me!

Thanks moomins!
