The doctor isn't here yet, but the contractions are definitely getting stronger. You can tell, because The Wife isn't really able to talk or move much during the contractions. They are painful, but not horrendously so. She said it's somewhere between a kick in the nuts and a really good work-to-failure exercise pain.
Better her than me. If it was me, I'd be curled up in a fetal position, sucking my thumb. As it is, I'm sitting next to her and typing up some papers for my schoolwork.
