Don't hug women.
This caught my eye, because I realized I don't hug women.
Women get a handshake, or a kiss. Old, young, family, friend.
Of course, running up to women you just saw last week and kissing them will ramp up the creep vibe in short order, so a friendly nod and wave will do.
Hugs are for socially awkward losers. It is appropriate to let women hug you.
My daughter's boyfriend seems to have this instinctive aloofness--the lad shows promise. But he needs to work on his interactions with men.
