If someone put up a post and captioned it “happy birthday to my favourite little sister” this is clearly saying they have a favourite out of their sisters to me? The other two sisters are older than the person posting the post don’t know if that changes the context.

If you only have 1 sister, its fine.

If they’re the only little sister then by default they’re the favourite little sister.

Agree with all the other posters - I always call my brother “my favourite brother” - I only have 1 sibling

Hollowvoice · 23/09/2026 16:28

I also have a favourite little sister.

(I have only one sister)

I'm pretty sure that this is a very standard script from printed birthday cards. My favourite Grandma, My favourite baby brother.

Hallmark cards aren't considered purveyors of rage bait and cited as an organisation that tries to break up families.

I agree with everyone else. The "little" changes the context. She's the only little sister, so therefore she's the favourite little sister by default. She's the only possible option.

You're trying to take offence where there's none to be found.

Ablondiebutagoody · 23/09/2026 16:23

It sounds to me like the poster only has one little sister, so no need for anybody to take offence

BitOutOfPractice · 23/09/2026 16:22

Obviously it’s a joke - as others have said. Do you not get it? I call my sister my favourite sister because she’s my only sister.

I mean it’s a pretty obvious / common joke. How can you not get it?

I think MN is having a moment today 🙄

TheJoyousHiker · 23/09/2026 16:22

If she is the youngest of all the siblings, then she is the littlest, so it’s a play on words really. Same as if someone said my favourite middle sister or oldest sister.

Justploddingonandon · 23/09/2026 16:21

Surely this is just the same as my telling DD she's my favorite daughter (I only have one).

runnerducky · 23/09/2026 16:21

It’s a common joke when someone is the ‘only’ to say they’re your favourite.

‘My favourite granddaughter!’
’I’m your only granddaughter!’

And so on.

Raptors · 23/09/2026 16:21

They only have one little sister. That's the whole point of their message. Confused

cramptramp · 23/09/2026 16:20

They only have one little sister. So no one else can be the favourite little sister. I call my daughter my favourite daughter because I don’t have another daughter. It’s just a joke. Anyone who takes umbrage must be very over sensitive.

runnerducky · 23/09/2026 16:20

It’s their only little sister? That’s the joke?

nomoreraintoday · 23/09/2026 16:19

Only little sister = favourite little sister by default surely? (Also least favourite but that doesn’t sound as good on Facebook 🙂)

Biscuitsforbreakfastt · 23/09/2026 16:19

Of course it changes the context 🙄
