Milk and Biscuits

It was a small moment, but I was so charmed by Ada this morning: 

Ada (holding plate of jam-slathered buttermilk biscuits): can I have some water to go with my biscuits?

Me: Are you sure you don't want some milk?

Ada: Which would be better with biscuits?

Me: Well...milk goes very well with biscuits and jam.

Ada: Okay!
