Most 15 year olds look like young adults. How are we supposed to know who is under age when they have gone through puberty?
And that 12 year old was hard to tell how old she looked but because I have seen the movie and know the actress (not personally), I knew she was about 12 or 13 in the photo and knew what movie it was from.
When I was 12, I looked 15 to some people, most thought i was 14 now what if 16 year olds were to be attracted to me because they thought I was their age. What if a 15 year old guy was attracted to me because he thought I was older?
When I was ten at Disneyland, there were these two teen guys looking at me and checking me out. Mom didn't think it was a big deal. But it bothered my uncle Alex. So he told them off by telling them my age and guess what, they left and stopped looking at me. They thought I was older because I was tall for my age. Not all teens have breasts or a woman's figure so that didn't even tell them I was no a teen. I didn't even have boobs at ten nor a woman's body but not all teens have a woman's body yet nor boobs.
At 12 I did have big boobs and a woman's body so of course people would think I was older. I cannot always tell the difference between a teen and a young adult. But thank goodness I am married.
