Trying to cheer up

After Great-Grandpa died last Tuesday, I was trying to explain death to Thing One.
Thing One: Why you have tears coming out your eyes?
Me: I liked Great-Grandpa a lot. I thought he was real swell. And I'm sad I can't talk to him anymore. And Great-Grandma is sad because Great-Grandpa was her husband. And Grandpa is sad because Great-Grandpa was his daddy.
Thing One (after a pause, as if to process that): I'm going to make cards for Great-Grandma and Grandpa.
Then he ran off to his art table to get started right away.
