Oh honey, you’ve probably noticed that things around the house have been a bit unhappy recently, and you are old enough to know what’s going on. We’re trying to get me pregnant, and well I’m worried he just can’t do it any more! He can get it up, mostly, but I don’t think it’s going to work. We’ve been trying for MONTHS.

Don’t try to deny it, I’ve seen you looking at me. It’d be perfect. You look so much like him that no one would ever suspect a thing.
