I've been hearing my whole life from sensible and sensitive people about how we shouldn't take things for granted. And while it is pretty good advice — right up there with not judging a book by its cover and looking before leaping — I've found that even the most rational and reasonable of people still do it anyway. I should know. I'm one of them.
Taking things for granted is one of life's simple pleasures. What can be more comforting than assuming that something, or someone, will always be there for you? Do we really want to live our lives in constant worry, wondering when the people and things that bring us joy will go away? Isn't it better to go to bed at night secure in the fact that they will be there when we wake up? The answer should be obvious.
