If in a hospital bed sitting there pushing out HIS damn kid, you better believe I wouldn't be okay with it. If his job is that freaking cruel that his own child ain't important then f-ck that job, you find a better job because what's going to happen once they realize they got you to miss the birth of your own kid, they are going f-ck you right up the azz with other stuff.
"Sorry, can't make it to Little Johnny's birthday, important meeting"
"Sorry, can't make it to Little Johnny's graduaton, important meeting"
"Sorry can't make it to little Johnny's wedding, important meeting"
"Sorry, I couldn't make it to anything important to you, Johnny..."
That's a one-way road to divorce and kids who want nothing to do with you. If he is going to let that job grip him by the neck so bad, then.... I'll be at home waiting with the divorce papers. If that meeting ain't about saving the world for ultimate destruction, your azz better be there. I don't care if you died during my pregnancy, rise from the grave and COME TO YOUR CHILD'S BIRTH.
