Yes, it's very weird. The 'father to be' has never handled news like this before. (His wife has, but now his wife is totally backing off with this issue, and he's doing it.)
I'm thinking it could because this is the one thing that this couple has that none of the other people in our group has experienced- all other life stuff-we've all completed around the sametime. Oh well. I figure my best bet is just to ignore him.
