3 out of 4 of my abuse situations - ALL of which were ongoing, repeated events - were at the hands of people i knew and who were assumed to be safe (home, school, scouts.) only once was it a stranger (fitting room of a clothing store) - and then "only" one-off.
"the scariest thing about abuse of any shape or form, is, in my opinion, not the abuse itself, but that if it continues it can begin to feel commonplace and eventually acceptable."
