How do the Gladers ask the Creators for something that they need? What would you ask for from the Creators, and why?

They wrote a note and put it in the box.

Thomas was surprised. "You mean, you can make requests? Supplies you want?" Why would the people who'd sent them there help so much? "Of course we can. Just drop a note in the Box, and there she goes. Doesn't mean we always get what we want from the Creators. Sometimes we do, sometimes we don't."

Your last question wants your own opinion.
