I was in the adjoining room as the boys took a bath on the morning of Earth Day.
Raf: it's earth day. It's a special day about the earth.
Charlie: I know. It's special.
Raf: what are you gong to do about earth day?
Charlie: it's about poop.
Rafi: it's not about poop, Charles. It's about the 'Earth is Good'. What are you going to do... pick up some grass...?
Then they started talking about which train set they wanted.
