"The moral of this story is that sometimes, you can attempt to make all the difference in the world, and it still is like trying to stem the tide with a sieve.

The moral of this story is that no matter how much we try, no matter how much we want it... some stories just don't have a happy ending."

"When someone leaves you once, you expect it to happen again. Eventually you stop getting close enough to people to let them become important to you, because then you don't notice when they drop out of your world. I know that sounds incredibly depressing for a thirteen-year-old, but it beats being forced to accept that the common denominator must be you."

"I have this math teacher, Mr. Allen. He said that when you're a point, all you see is the point. When you're a line, all you see is the line and the point. When you're in three dimensions, you see three dimensions and lines and points. Just because we can't see a fourth dimension doesn't mean it doesn't exist. It just means we haven't reached it yet."
