Garrett Matthias, 5, thought about what his funeral would look like one day. He didn’t want a solemn gathering; he wanted a carnival-like atmosphere.

“Funerals are sad,” his obituary said. “I want five bouncy houses (because I’m 5), Batman and snow cones.”

When he died, he said he wanted “to be burned” and “made into a tree so I can live in it when I’m a gorilla.”

And after he died? “I am going to be a gorilla and throw poo at Daddy!”

He shared all of this — and much more — in various conversations with his parents over about 10 months battling a rare form of cancer.
