AB had a nice place to have interactions with her peers. They could be together to do lots of fun stuff at her house, I feel. Kids have always done stuff they aren't supposed to, but if they are not dysfunctional, doing the inappropriate things aren't their total focus in life. I think teens that are wrapped pretty tight have a good time doing things that are acceptable with a little experimentation on the side.
My kids, who are all grown ,are great adults. My middle child, who I thought was perfect, told me, "Mother, you are so naive. All kids experiment."
And that's what I think is true, considering how my one daughter really was so perfect and apparently did experiment.
I just think that these teens who are friends with AB are in a very strange place in their psyches.
