I Think Kids Are Funny

My nephew is 4 and barely 3'. He tried climbing the rock climbing wall set up on the playground but couldn't reach the footholds.
"Maybe it's for taller kids," I suggested.
"I'm tall!" he insisted, then failed again. "I fink I'm not tall."
I felt bad for him, but then he ran off to climb up a slide and scream "Imma lion king!"
