In addition to being absolutely adorable, I felt that this warranted mention because of how unusual it is. It is far more customary for children of this age bracket to look up at me with a confused, alarmed, or flat-out terrified expression that screams, "HOLY MOTHER OF GOD HE'S LIKE EIGHT FEET TALL AND HE'S GOING TO COME FOR ME IN MY SLEEP." This felt pretty sweet. I love kids.
Disclaimer: I'm only 6'4" (though a doctor claimed 6'4 1/2"). I was just speaking figuratively. :-D
