I've always been able to tell when the ladies are receptive. It's a vibe, a mood, a look, a smile.
Sometimes it's just a casual harmless touch in a crowd like a train or club or a concert.
An 'honest knock' can lead to a great conversation. That (oh sorry) has led to many an encounter.
Even if hubby is there, if he's into it, he'll just smile and let her go.
