I grew a beard over my vacation and as usual, became an object in the Beard Wars. The women who like beards (it's always women) come out and say how much they like it. After the beard comes off, the other side takes the positive-reinforcement field, and the women who didn't say anything before now say how nice a clean-shaven face looks, while the first group stays quiet. Kind of amusing.
(Of course, the first group may mean "I like the beard - that way I see less of your face," while the second may mean "glad you got the rat-nest off your chin," but they never say it that way.)
