Ain't it funny how smart Dads get as we get older ?
From my experience having and being a dad:
First they are really smart and know everything
Then they get really dumb, rocks are more intelligent
Finally, somehow, they revive from the haze of stupidity and start to get smart again, and though they never attain their original smartness, they do get pretty close.
Judging from my older kids, I'm descending to the rock level. At least my youngest kids think I'm pretty smart
After that...its going to be a few years before I start to get smart again.
It is wonderful, though, when we come to our senses and start to realize again what is important in our lives, and it isn't money or stuff. It isn't easy being interested in things that don't really interest me, but sometimes we have to put that aside for the sake of relationships.
I wish the best for you and your dad.
