I was over at a friend's house having coffee with her on the patio. I've known her from work for a couple of years. She's my age (48) and is divorced/single, but her daughter is a 20 year-old college student who lives with her. Her daughter's boyfriend lives there too. Evidently they are potential marriage material.
My friend disappeared for a bit, came back out, and said don't go in the house to get another cup of coffee. I asked why, and she said, "Maya [her daughter] is screwing her boyfriend in the living room. We need to let them finish."
What?!?! I don't have kids, but if I did, I'd make them be a little more private.
