When a hand is outstretched as an offer of friendship, such as a handshake, but the other person does not respond.
If someone offers a hand to shake and I don't notice or reciprocate, the person asks, "You gonna' let me hang?" In other words, are you going to offend me by publicly declining my offer of friendship.
My hand is now obviously extended or open. Will you intentionally ignore it to humiliate me?
