Clara and Marc are playing with a puzzle on the carpet right behind me. Here is the conversation...
Marc- can you find that piece?
Clara - no, say "pig can you find that piece"
Marc- ok, pig can you find a fish?
Clara - ok, Here it is.
Marc - good little piggy!
Clara - thanks, I'm a pig right now but in a few weeks I'll be the princess again.
Marc- great (laughing) I love my princess!

They've been having odd conversations all evening.
