Journaling (warning, contains a word that some people might find offensive):
(Transcription of a conversation I had once with a cute, bright, and talkative two year old.)
“Mommy, look! It's Thomas and Pooh-sie!”
(Giggling in shock) "Oh, you've found Thomas and
PERcy, that's awesome honey."
"Mommy, Thomas and Pooh-sie are friends."
"That's right honey, Thomas and PERcy are friends."
"Mommy, Thomas is blue, Pooh-sie is green!"
"Honey, his name is PERcy. Say after me: PERRRcy."
"No, dear. PERRRcy."
"Very good. PERcy! And you are right, PERcy is blue."
"No Mommy! Pooh-sie is not blue. Pooh-sie is GREEN!"
(Giggling my butt off) "If you say so, honey. You're the expert!"
(I have the whole thing on film, and I'm so glad I do! In 14 years... blackmail material! LOL!)
