Why do some men take their wedding ring off and on during meetings?

Answer 1

The question wasn't that clear. If he takes his wedding band off and puts it in his pocket at a meeting it's an odd thing to do unless there are people from another company in that meeting and he is trying to impress a woman and doesn't want her to know he's married. If he is flicking is ring on and off while at the meeting, but not putting it in his pocket this can be a sign of nervousness or a habit. Some people will roll their ring around on their finger out of habit or nervousness and it doesn't mean they are trying to find another woman to have an affair with.
