This is about Keller's best friend Vance.
They've been friends [at least their parents have] since birth.
They 'feed' off each other. One starts to laugh, the other starts to laugh. One starts to scream, the other starts to scream. One of them calls themselves 'silly', the other calls themselves 'silly'. It's pretty hilarious.
Vance came over and played in the water last week. They laughed, they ran and then they did this:
Mind you, Kimber [Vance's mom] and I had filled up the buckets so they could dip other buckets in them. Keller and Vance thought they made better swimming pools than buckets.
Oh the joy of being 2!
