My 16yr old daughter wants to have a sleepover with her "best friend" who is a boy. He was described as her best friend for a while, then another boy described as her best friend. Now she's having a sleep over with the first boy. They have been friends since yr3, and are part of a larger group, including girl's twin sister. Usually they all do things together. Is very unusual for the two sisters not to be doing something together. Girl's twin sister made a joke with her dad about it being sexy time, but then said no, it's nothing like that. What do you think? It would be good to get some ideas about how to react to this.
