Hey married guys, when's the last time you gave an eye-wink to your wife?
A well-placed wink communicates volumes. It might be an inside joke, a sign of affection, or a "don't worry, I think the same way you do about this." But regardless of the communication, the point is that a wink is a communication between two people that others are not privy to.
How are you doing at that? Do you have special communication with your spouse?
(That counts too)
