I can't help but smile, not for your struggles, but for the club you are joining. Kids are amazing, they are my greatest source of inspiration and frustration. My daughter is finishing high school this year and my son is a few years behind.
Years of trekking them through the bush and (to my wifes chagrin) up mountain paths, caves etc. have given them a special appreciation for dads 'alone' time. I think / hope it has shown them that it is okay in this world to disconnect from the facetwitterbookingnmess that surrounds us (oops is my bias showing).
The vision definitely changes when kids are introduced into the picture, but it never goes away.
