Charlie, that is one of the best essays I have ever read -- publication-worthy, even.
You have obviously poured your heart and soul into every word, and it certainly shows.
Yes, we who are fortunately enough to be parents can understand. I think it is a natural feeling to look at our kids and wonder how our parents felt about us.
Charlie, if you don't ever publish this, please print out a few copies for your own sons. Give it to them at the appropriate time -- when they turn 21, or when they have children of their own.
And Charlie? Have a GREAT Father's Day . . .
