How to get small and big

Today in the playroom with super amazing K. I had this conversation:

K: We can get very small and get into the truck (looking over at small truck on floor of playroom).

Benjamin: How shall we get very small?

K: We can look at the stars to get small.

Benjamin: Wow! what a great idea! That's an amazing way to get small!

K: And then we can go back to our normal sizes.

Benjamin: And how shall we get back to our normal sizes?

K: We can play with our friend to get back to our normal sizes!

Benjamin: Wow! I *love* it that you told me we can get back to our normal sizes by playing with our friend! And what friend shall we play with?

K: I'll play with you--you're my friend!
