part of adult life is taking responsibility for the situations that you put yourself into. Any "man" his age would be ashamed to be talking to, hanging out, or interacting with a woman who is close to 18.
You can't just claim, "I didn't know" that is such an irresponsible way to look at it.
dude looks like the love child of Travis barker and a rat, no adult woman would ever be attempting to get his attention .
