My son likes to "read" to his sister. It's quite cute. The other day, I overheard the both of them in her room and he was reading her a Sesame Street book. Here was their conversation...
K: " A, who is that?" (pointing to a picture of Elmo)
A: "that elmo."
K: "good girl"
K: "what color is that?" (pointing to something red)
A: "that boo." (blue)
K: " no...good try, that's red."
A: " that wed."
What a great little teacher he is! I love when they get along. :)
