Funny that I didn't have a dad for the first 20 years of my life - or not a permanent one, and certainly not the biological one - and now that I do, I treat him as if he'd always been there.
But the best Fathers Day thing I've read this year was from Enid-Raye Adams' blog, which quoted another one, and can be found here. I'll just quote her conclusion:
To all the Moms out there doing both jobs, Happy Father's Day.Good stuff.
And to the Dads that stay and do the work, you are a treasure beyond description.
