What not to do when the mother of your children goes back to work (at your request).
When your loving wife is in the shower, don't barge in on her with your 10 month old daughter, stand there and ask what she's doing. This may be the first time she's had a quiet minute to herself all day. Don't take that away. And don't use the baby as an excuse for your lack of respect. I'm pretty sure the baby doesn't "need to see" her.
If your wife depends on you to be home at a certain time so that she can make it to her job on time, don't call and say you're going to be late. She may not make as much money as you, but that doesn't make her job less important. And don't act like there's nothing you can do. Your boss is well aware of the fact that your wife works at night.
When you finally do get home after a long day of sitting comfortably at your clean desk alongside other grownups, don't complain that dinner's not ready and the kids haven't been fed. Throw some water in a pot, boil it, and make pasta. You're a big boy, you can handle making something for yourself. Your wife is on her way to her 'other' job.
If your wife also works on the weekends, don't wait until 30 minutes before she has to leave and ask if you have enough time to shower. The answer will always be no.
