If he was aware a woman was being harassed at work or if a friend was harassing a woman socially.
He's 17 and a timid little thing, speaking up doesn't come easily to him, but he does have a strong sense of justice and has been known to stick up for the underdog in the past.
Anyway, he didn't think much about his responses, but said at work he'd report it to someone who can help, that's what they're told to do in their diversity training.
Socially he'd tell the friend to "dial it back a notch".
Is that enough?
