(random thought.. mother's boyfriend is the witness right? Could we have a little jealousy be at the core of this?)
.. I dunno, but that's one that didn't cross my mind. Mom's boyfriend is probably a creep and would like the chance to get the daughter alone and take a little delight in said daughter... my thought is he would like to whether the girl wanted to or not. It's creeps like THAT who perpetuate the myth that WE'RE the ones thinking that way. Psychological Projection.
Peace, Love and LET THE MOTIVES BE CLEAR!!!
