Church facilities for the sick

A little girl and her mother were in church when the girl started to feel ill.
"Mommy, can we leave now?" asked the girl.

"No." replied Mom.

"I think I'm gonna throw up."

"Well go out the front door, walk around the back of the church and throw up behind a bush."

A few moments later the girl returned to her seat.

"Did you throw up?" asked Mom.

"Yes."

"How could you have gone all the way around the church, throw up and be back here so soon?"

"I didn't even have to go outside. They have a box right by the front door that says 'for the sick'."
