If a 40 yr old married man winks at a 40 year old married woman he has known for a short time, is he flirting?

From my limited experience, there are several "levels" of flirting. From actions as seemingly insignificant as the accidental brush of an elbow, to the obvious pick-up line.

No, he is just being friendly in a flirty kind of way. Older people (30+) don't play the same relationship games that we used to when we were 15-25.
Reply:Was there something he said just before the wink? Sometimes people will do that to signify an inside joke or a dead-pan one-liner.
Reply:I would say yes. There are very few circumstances in which winking at someone would not be flirting, such as if he's telling a joke.
Reply:Either that or he's got something in his eye.
Reply:well there can a actraction between both of them but their both diong wrong cause the 40 year old wonmen knows that he ids married and she still being there.
Reply:dust in his eye, or begining of cataracts, latter is a joke!
