My wife was an adult when she began studying...alone in a new town with a new baby...Ripe for the pickin'.
I however, was raised as a 3rd generation witness. My wife is still "in" but can fully understand my reasons for leaving...even though at the present she hopes it's temporary. She and I both see the vast difference in our situations. I chuckle at her because of her relative age "in da troof"...and she laughs at my awakening as an individual. This was my first year being politically active...she said "Oh, I remember being like that when I was a freshman in college."
I agree that when a person raised in it leaves...it's a totally new experience. You have to really take time to find out who you really are. I think that's why some go hawg wild for a time...then they settle into the identity that they've found for themselves.
