Your girlfriend's shirtless brother.

David Sedaris, in his book When You Are Engulfed In Flames, writes of visiting his father and going to a cocktail party on the street where he grew up in the ’50s, ’60s and ’70s. The teenage son of the hostess was flamboyant and used female pronouns when referring to Sedaris’ father. The hostess casually explained that her son was gay as if Sedaris hadn’t already figured that out. Then Sedaris remembers how no one could admit to being gay when he was young. Instead, you tried to date girls who were appreciative of sensitive boys. The mothers loved boys like that, especially if you told them you weren’t interested in having mere sex like dogs. You wanted to make love after connecting on a deeper level, and that might take ten years. Sedaris said that it was better to explain this to your girlfriend’s mother on the back deck while the girl’s brother was mowing the grass without his shirt on.
