The wife relayed his reaction to seeing his first rainbow last week.
They're driving along and there's a giant rainbow between two hills.
The Wife points it out, "Look Fuss! It's your first rainbow!"
Fuss, after an initial burst of excitement, becomes subdued and notes-
"Uh.....Mama? It's only HALF a rainbow!"
She attempted to explain that's just what rainbows look like, but he was prepared-
"Mama...there's no BLUE in it."
Proving once again that he is indisputably my son.
