Should I tell you what he was doing, or do these pictures tell their own story?
Parents, without a doubt, and even the best of them, will drive you batshit at each and every chance they are given. But then, there are those moments where you look at them in action and have that instant sense of identity. Where you realize that your crazy-assed apple didn't fall or roll that far from the tree, and that's perfectly okay.
This would be one of those moments.
I love you Dad!
