This is a weird one...I've noticed a change in the way some women are reacting to almost 15yo DS and his friends, I thought it was just my imagination but even (ASD) DS who is pretty socially clueless has commented on it.
Typical example seems to be when I drop DD off at dancing, I do it en route to taking DS and his friend to Cadets - one week they were in their ceremonial uniform so looked older and I guess quite masculine, and some of the other mums were almost flirting with them - very complimentary, patting their arms etc, and there is the odd near the knuckle comment said to make them blush.
Another time the boys were talking about when a gang threatened and chased DS' friend and one of the Mums hugged him - kind of reminded me of the way Nurse Gladys used to hug Granville in Open All Hours for anyone else old enough to remember.
It's all very innocent on the face of it, but DS' said yesterday "Ugh they are embarrassing me" - his friend said he quite liked the attention, but I think if it were adult men and a teenage DD I would feel extremely uncomfortable about it.
DH reckons it is probably my friends reminded of their teen years and just having fond memories of their youth 
I was going to name change but thought I'd be accused of being a teen boy trolling. I just wondered if anyone else had noticed a change in behaviour from their friends (especially if they haven't got teen boys themselves)
