As a father of eight, I can say that I know you've missed a lot! A lot of dirty diapers, sleepless nights, broken and lost property, bickering, smart mouth, frustrated wife ...and the list goes on and on... to include the kind of love, fun and joy that you can only get from your own kids. I'm sure my wife and I have missed a lot of quiet mornings, interesting hobbies, peaceful nights, exiting trips etc. It's nice to know that you're truly content...
...and that we'd never trade places, and that we both can feel good about that.
I like your attitude, really. You can see both sides of the issue and not be upset. I wish I were that flexible. Unfortunately, I am not. Noise, unrest, and all that sort of thing would have sent me to an early grave, so fortunately for me, I could see my limitations and acted accordingly.
