Me, shoving a magazine article about teenage hormones toward D.: When you have a minute you really should read this. We need to be talking.
D, panicked by hearing the words "We need to talk": About us?
Me, pointing to the title of the article: No. With Moon. It says we should have already talked to him about....
D: Oh...(making a circle with the thumb and forefinger of his left hand, then moving it up and down over the pointer finger of his right hand)...about the ee-er, ee-er?
Me: And about the..."special" dreams.
Based on the quality of that conversation, I'd say our sex/hormones/masturbation/nocturnal emissions talk with Moon should go off without a hitch.
