When I was 12, I looked about 16, but I stayed looking that age for a long time. I still look much younger than my age. Every so often, someone says something to confirm this. I was speaking with one of the mums when our kids were in a class and we discovered we were at the same uni. She asked what school I went to and then said, 'You'll probably know X'. I asked what age she was and worked out that I was finishing uni when the girl was just starting secondary school. The mum was really taken aback. Then on Saturday, we were at a museum and there was a fun 70s quiz. The guy running it said to us, 'You two won't remember this, you probably weren't even born then'. My husband is 43, NT with many traits. I suspect the guy was younger than him.
