Huh. Whaddya all make of this?
Dr. Mrs.' friend, let's call her Kim (fun fact: a former Miss Cherry Blossom), texts Dr. Mrs. last night. Kim overheard her daughter and her daughter's (female) friend, who was over at their house, playing in daughter's bed room. Game involved "pretend you're tied to the bed."
Kim became concerned.
When Kim heard the next part was about "clothes" she decided, welp, enough of this, and went into the room to talk to the girls. Daughter's friend explained this game was called "boyfriend and girlfriend," and boy had tied girl to the bed because "he didn't want her to go to her room." The object then was they would "sleep together," although Kim inferred from context this meant sleep, not "sleep," together.
Kim's daughter and daughter's friend are 8.
So. Um. Wot?
