"There are infinite numbers between 0 and 1.  There's .1 and .12 and .112 and an infinite collection of others.  Of course, there is a bigger infinite set of numbers between 0 and 2, or between 0 and a million. some infinities are bigger than other infinities.  A writer we used to like taught us that.  There are days, many of them, when i resent the size of my unbound set.  I want more numbers than I'm likely to get, and God, i want more numbers for Augustus Waters than he got.  But Gus, my love, I cannot tell you how thankful I am for our little infinity.  I wouldn't trade it for the world.  You gave me a forever within the numbered days. and I'm grateful." -John Green, The Fault in Our Stars
