Nope. You're wrong. I said earlier, as a generalisation, NOT aimed you personally...
Taken from my post at 17.59
The reason people are offended, is because even though they are old enough to be a grandmother (and are the average age of a grandmother - according to Government statistics, around 49-50,) in their head they think they look like they're in their early 30s.
Everyone else is seeing someone who looks their age though. (As everyone does - within 3-4 years.) So even though someone of around say 49-51 thinks they look 33, everyone else is seeing someone who is around 50. No-one thinks you look 33.
I said someone who is 49-50 is not going to look 33, they will look their age, so that is why people can easily think you could have grandchildren. I merely said that some people were under the impression that they look 15 years younger than they are. (You see it a LOT on Mumsnet.) So they are automatically offended if someone thinks they look older (than they think they do!)
I did not aim anything at you. It was a generalisation based on what you were saying. I was not 'nasty.' I stated facts. That everyone pretty much looks their age, and that some people think they look much younger than they do. And that's why they are offended when someone says something that implies they think they're older than they think they look (or GASP! thinks they are their actual age.)
Upshot is, it's NOT that weird or offensive for someone to assume someone who is 49-50 could be a grandmother. 74% of almost 900 people think YABU, and many comments on here suggest it too. Maybe you should just accept YABU.
And @Iggilypiggily you may think people are being 'nasty' to assume a woman of 50 picking up a 5-7 y.o. is the grandmother, but most people will. That's just the way it is. Despite lots of posters on Mumsnet saying they and everyone they know had their first child at 42, and had another 1 or 2 in their 40s, most women will have their first by 30, and the last one before they are 37-38.
I'm all talked out on this thread now, and am just repeating myself at this point. So I'm out.
