Oh, that's so sad.
Can you be more concrete with-him ... like, my son will ask about going to jail at his age, and I'll say, no, you go to juv. detention until you're 18 (for breaking into a car, for eg.), then you go to jail, unless it's something really awful, like murder, then it's federal prison.
We don't even talk about the hereafter. It's too big of a concept and too discouraging. Besides, then you get into the BIG what-ifs, like, "If God forgives everyone if they repent at the last minute, and he forgives Osama bin-Laden, does that mean that he and I will be in Heaven together?"
Arrrrghhh!
Hey, I just realized you're pregnant. Congrats!
