1) "It's your JOB to be their mother." [The implication was clear that she's no hero, so don't expect any special treatment "just" for being a regular ol' mom. This, after they'd both spent several hours over the previous week making stuff for their kids' grandmothers without any suggestion that his mom was "just" doing her "job" as a grandma.]Here's another hint: if you see nothing at all wrong with either statement, you SUCK as a human being, and as a husband/significant other/co-parent/human being. Go live in a cave. Alone. Far away from your family.
2) "I'd probably have done something for you today if you hadn't gotten so fat and ugly." [She's not ugly, and the 'fat' is from baby #3.]
And, ohbytheway, what you do when "Mom" isn't around to deal with the kids? That's NOT CALLED "babysitting." It's called "parenting."
