a large majority of this 'talk' revolved around the goings on of male puberty, the teacher stared talking to them about facial hair and shaving. My son shakes his head when the teacher talks about getting a gillette and a can of goo and the teacher notices and ask him about it, son says "My dad is going to teach me proper old-school shaving and how to make my own lather with a badger hair brush"
teacher looks surprised and nods approvingly (according to the boy). of course when he said that the other kids started asking about traditional shaving. hysterical
