Quotes
We've got to talk about this fear and decide there's nothing to it. I'm frightened myself sometimes; only, that's nonsense. Like bogies. Then, when we've decided, we can start again and be careful about things like the fire... And be happy." - Ralph. This quote tells us how much of a kind thoughtful leader he is and how he takes charge in stressful situations
