LW1 I have to wonder if the husband's parents are helping them with the down payment or some sort of financial arrangement because LW mentioned the fact they are generous.  Otherwise, I can't think of any reason why they would know about the house hunting details.  Just a suspicion, but I have the feeling they involve the in-laws in their business because they need them--money, babysitting, etc.  If that's the case, they need to cut back on asking them for help.

Also, does the in-laws know the son hated the pillow tradition?  I can't see where that was said.
