While walking around the neighborhood this morning with Jaimito in his stroller: "Look, Jaimito, a helicopter."

"A copper-copper?"

"Yes, a helicopter."

"Oh,
I see it. I see it," he exclaimed excitedly. "Ooo, Daddy, da’
copper-copper, w’ d’ ting, dat go ’round, ’round ’round, ‘n’ it go up
‘n’ up." He threw his hands up in the air.

"Wow, little boy,

smart, you must take after your Papa (grandpa) Jim."
