“Eventually, it sinks in and you become him,” Batman told me. “It feels like I have a responsibility that’s beyond a normal person. And that responsibility is to be there for the kids, to be strong for them, and to make them smile as much as I can.” He understands that might sound corny, but he doesn’t care.

Batman stepped off the elevator on the fourth floor of Children’s. Spider-Man and Wonder Woman were there too — both professional actors from talent agencies, on the clock. He picked up a little boy and said, “I have a present for you.” He shook hands with a father and handed him a yellow rubber Batman bracelet, saying, “This will bring you good luck.” The father said, “We need good luck.”…

Batman revved the engines and blasted the audio system — the Batman theme song. Na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, Batman! He revved the engine some more. The little boy didn’t want to say goodbye, but his mom told him, “Batman needs to go fight the bad guys.”

The little boy cried.

“I want to go help him fight the bad guys,” he said.

His mom said, “You need to go help your sister fight cancer.”
