From my 12-year-old son on my 60th birthday:

To dad:

This year has been awesome with you.  I can’t think of a time in which I have not looked up to you as a great role model.  You teach me things every day — maybe without you even knowing.

I love the fact that every day I get to see you during school and give you a hug.

In my opinion I think there are no dads that meet all of these points except you.

I want to say thanks for taking your own time to come to all of my sport events and being my baseball coach.  I also want to say thanks because I love it that you like to check over my written work and help me on math problems that I do not get.

Love,
Louis

p.s. — Love the millennial outfit.

To clarify a couple of points in this letter:

(1) I was serving as a long-term substitute teacher in my son’s school (but not in his grade) during the final 9 weeks of the school year.  That’s why he was able to see me every day.

(2) My son saw me wearing a suit with tennis shoes and labeled it my “millennial outfit.”
