Pebbles: A Conversation With Luke

While reading tonight’s story for homework….

Luke (reading aloud): Sandstone is one kind of sedimentary rock. It is made of grains of sand, mud, and…. pue…. puh…. puddles?
Me: Try again.
Luke: Poodles?
Me (snickering): Are those D’s?
Luke: Pubbles?
Me: Almost. Is that a U?
Luke: Pebbles! What is a pebble?
Me: What do you think it is?
Luke: It’s a little rain drop that makes a puddle.
