The Eye of Sauron is an eye of your wife, the ever seeing eye. The eye that moves a little to the right, a little to the left, trying to get a glint of you whereabouts that day. Measuring and assessing where you have been, where you have roamed, did you drink, or went to a strip bar, whether you were stuck in a casino..
There is no escape from the eye, it sees all. No need to wash your suit, rinse your mouth, or subtle control of motion, she knows that you drank all night with your buddies, she saw it with her Eye. All you need to know is that you will not be getting any for at least a month.
Beware of the eye
