My mom was in labor with me for 30 hours. After waiting at the hospital all day and night, my dad (not in the airline business) said, "the heck with it" and went on to work. They called him I has been born. He told them he would try to drop by for a few minutes after work.

I was their only child. They were married for 63 years.

I don't think my mother ever forgave him. Be there for your child's birth, if humanly possible.
