-how you say usic instead of music
-that you came upstairs to tell me that "daddy's playing with the vacuum cleaner."
-that you know all the words to "I got dirt on my head" and are currently obsessed with Groundhog Day
-when we were all in the bathtub, you said we were making a "naked train!"
-that you tell me you are going to poop on your toilet, but instead you take a huge dump on the floor
-you love to have a "tato party" (god, how you love french fries)
-how constantly inform me of everything that is going on - "that's a big truck." "he's wearing pants" "I'm riding the the car."
-that you know all the words - and will sing - "Everybody Sing the Blues" and "Mama Tried"
I am sure there is more, but you want to play trains.
