Beard Etiquette

Sitting around the kitchen table eating Wendy's Frosties, Scott gets the shivers and tries to describe them to us. He says that his body sometimes "goes like this". I explain that his body is trying to warm up by moving really quickly. R notes that we also often get goosebumps when we're cold. I explain that this is another way that your body tries to help warm you up, but we don't have very much hair on our arms and legs, so it's hard to say how much difference it makes. The following conversation ensues:

S: Cam has the most hair on his face.
D: Right. Which of your uncles have hair on their faces? Ross?
S: No.
D: Luke?
S: No.
D: Brad?
S: No.
D: Joel?
S: No. [notices our reactions] ... yes?
D: Right. Taylor?
S: Yes?
D: Sometimes.
S: Yeah. Sometimes he cuts it off.
D: What about Mom?
S: No!
D: What about Katie? Does Katie have a beard?
S: No! Girls don't have beards. Just boys.
D: No girls have beards?
S: Nope.
D: What would you say if you saw a woman with a beard.
S: I would say nothing.
D: [laughs] Yeah, that's probably the right thing to do.
