So when my dad listed me on facebook as a son, I sent him a brief email telling him thanks and that I appreciate him. He just sent me this response.
"I got your email from the 1st and I keep it in my inbox so when I come accross it every once and awhile it picks me up to know maybe I have done some things ok enough to be appeciated every once and awhile. thanks for the note--your still one of my heroes. love dad"
Yes, he has atrocious spelling and grammar, but that so not the point. I love him. More and more these days.
