When my younger sister was just fresh out of high school she answered an ad for light housekeeping. She and her friend went together, thankfully!! She went home and told my older sister about this weird guy. My older sister had answered the same ad a while back and agreed that he was scarey. They mentioned him to may dad, a detective at the time. Come to find out, he had raped a couple of young girls answering his ads. He served time, was out....and apparently at it again.
Doesn't hurt to err on the side of caution.
My young drunk cousin had to register as a sex offender because he pinched a waitresses rear end in a bar. However, now you can go to the registry and view what the offense is, the age of the victim, etc....I believe in doing my homework. I would still always err on the side of caution.
