"So, I was actually thinking this a couple of days ago, completely regardless of Father's Day, bu, for whatever reason, I didn't say anything, and so now seemed like an appropriate time.
It was when you heard about Sage, and you choked up and teared up and sobbed a little. I thought then, This is a man who can cry. This is a man who knows how to weep, and I admire that.
I admire that a lot.
So, I know you know that I love you, and that I admire you for all sorts of other reasons - your integrity, your work ethic, your love, your just being an overall great dad and great person in general.
But I don't think I've ever told you that I admire your tears.
I can't think of any way to say this without sounding a little ridiculous, but... I'm honored to be your kid. Thanks for being awesome. Really."
