SiL and friend keep commenting on my age.

Only read the first page of thread but 'did you mean to be so rude?' seems appropriate here.

I'd have to retaliate and say something g along the lines of how lucky I feel not to need all that Botox or how other friends are always so surprised that she's younger.
Or remind her she's 5 years younger, not 5 years old and it's time she left bitchy remarks behind now she's a mature woman in her late 40's!

"I know. I'm quite a bit older than you but I'm so lucky, I don't look it at all. Not a drop of botox or filler as yet!".......

I'd just calmly (but in a bemused manner) say something like 'do you realise you mention my age on a daily basis?' Every single time she says it. She will soon get the message.

“You’re fucking rude” rinse and repeat.
Or, “You don’t look so fucking hot yourself” rinse and repeat.

WhatsApp is the new school playground!

I think you have 3 options:
1 fight fire with fire and say what you really want to say.

2 "Can you explain why you have such a fascination with my age"

• and if you get a reason say "why /why's that then"

3 Completely ignore it. Don't even raise an eyebrow.

If you need to be in the group to be in contact with some of the other members, make a new group without the vicious bitches.

Someone three months older than me used to say “when I was your age” all the time. She was in the year above so obviously saw herself as older.

It’s just odd to even mention age unless it’s relevant to planning a specific birthday. The numbers mean very little once you’re in adulthood.

I would find it irritating to the point I’d spend time with less ageist friends.

Fun as it would be to make one of the rude comments back the best thing to do is as PPs have said repeat the same lighthearted answer every time, I'd go with something like 'better than the alternative'. Eventually she will realise that it's not worth commenting on anymore and will stop.

This worked well with FIL who repeatedly told me about DD1, who was a baby at this point, 'what a pity she has my mother's nose'. I just said 'donations for her nose job will be gladly received' and after a few more times of saying it he stopped. Weird thing was, his Mum had a beautiful elegant nose so I'm not sure what his problem with it was.

Petty people pass petty comments. You can clearly see that both are insecure about how they look for their age... Don't stoop to their level.
If it makes you feel any better, my toxic MIL keeps comparing my size 6 healthy physique to elderly alcoholic family members who have recently lost a lot of weight. I just ignore it, she thinks she's pulling me down 😂

Bide your time. Get her the worst 50th card you can find.

Bloody hell. They sound hugely immature.

I'm sorry could you repeat that ?

I'm sorry could you repeat that ?

I'm sorry could you repeat that ?

So that she repeats it three times each time a bit louder)

Oh...I thought you were being quietly rude, but I see given the opportunity to stop being rude you've just got louder and ruder.

What you have said is very ugly and that looks very badly on you.

Some rebuttals... along the lines ...
My body has done wonders for my age I've done so many things already -- and can/will do a lot more things/activities than most. I'm going strong/look forward to many health/happy years ahead....
Talk to me about my age when you reach my current age/when you're 53 if you are as fit/good/good looking/ active/ doing as many things as well as I'm doing/have already done by 52/53..

We all age/mature -- some mature more slowly and enjoy life...
Ageing is natural; looking at others ageing is not natural -- unless you're a full-time anti-age therapist/conman!!
To ask SIL & friend: Why are you so scared of ageing ???

HTH SIL & friend -- you don't need any help!!

Absolutely say that! It's perfect

"SIL has the misfortune of ageing terribly"

Ok, so that's why. Do you really need it spelling out. I's not about you. Nothing ever is.

Stop hanging out with them.

That's one great thing about getting older is purging useless people like that from your life

I wouldn't stoop to their level. Just smile and say "oh darling that seems like you issue. I'm really not that insecure." If she continues then I add " if I get to the stage of worrying about it I'll get your surgeon's details from you" all with a smile.

Honestly I'd shut them up by not associating with them any more. I'm fifteen years older than two of my closest friends and five years older than another, and can safely say that I've never heard anything like you've described. They are not kind and don't deserve to be called friends!

"Yes I'm older than you. But thank goodness I don't look as old as you"

Sincere kind voice; " are you really worried about getting older. Concerned because you mention everytime I see you... honestly don't worry, its great, i seem to have stopped giving a flying fuck about what other peoples opinions on me are, but I find just need to keep up the fitness levels up a notch.... if you need any tips, let me know...."

"Jealousy is a bitch isn't it. How's the cosmetic surgeries going?".

My age is not an issue to me.
😂😂😂😂😂😂😂😂😂😂😂

Mmm, like, you’ve never mentioned that before 🙄

Where does it say is a WhatsApp group?

Could you say something like: "The best thing about being my age is that I couldn't give a fuck".
