Promises are scary things. To keep them means relinquishing some of our freedom;to break them means losing some of our integrity. Though we have to make them today, promises are all about tomorrow——and the only thing we know for sure about tomorrow is that we don't know anything for sure! And it's not just the outer world that changes in unforeseeable ways;it's you yourself. 每种新的体验——新的责任, 新的交往——都会使你的想法改变!
