Wow. This may have been the first time I've wanted to punch a picture.
I think in the past I would have laughed or scoffed, but after reading so many horror stories in the last few years of women who's (usually ex-)partners have done or said something similarly awful when they were in labor/had just given birth, I'm not even sure it was a joke anymore. You'd like to think, "Ha! No one would really be that big an asshole!", and yet... it's happened way more than you realize.
For the record, Mr. Z was not one of those guys. That is why he is still living.
