My little nephew already knows his colors and that two and two are four. He's not too sure that being two is a good thing. He seems to know that he's been able to get away with a lot because he was a baby and now he's leaving babyhood behind.

Aw!

KK, it's very common for people to use mnemonics for the colours of the rainbow over here. I personally didn't learn any of them until years after I knew the colours - which always seemed to me to follow such a blindingly logical order that a mnemonic was unnecessary - but I did invent a song to help my little sisters learn them. They still sing it now they're in their twenties.
