“Even though there are no ways of knowing for sure, there are ways of knowing for pretty sure.”

“There is no way of knowing for sure whether or not you can trust someone, for the simple reason that circumstances change all of the time.”

“It is true, of course, that there is no way of knowing for sure whether or not you can trust someone, for the simple reason that circumstances change all of the time. You might know someone for several years, for instance, and trust him completely as your friend, but circumstances could change and he could become very hungry, and before you knew it you could be boiling in a soup pot, because there is no way of knowing for sure.”

“Members of your family might say they are working hard all day long, while you are off at school or clarinet lessons, but the only way to know this for sure is to follow them at a discreet distance.”

“As I am sure you know, when people say 'It's my pleasure,' they usually mean something along the lines of, 'There's nothing on Earth I would rather do less.' [...]”

“The phrase "in the dark," as I'm sure you know, can refer not only to one's shadowy surroundings, but also to the shadowy secrets of which one might be unaware. Every day, the sun goes down over all these secrets, and so everyone is in the dark in one way or another. If you are sunbathing in a park, for instance, but you do not know that a locked cabinet is buried fifty feet beneath your blanket, then you are in the dark even though you are not actually in the dark, whereas if you are on a midnight hike, knowing full well that several ballerinas are following close behind you, then you are not in the dark even if you are in fact in the dark. Of course, it is quite possible to be in the dark in the dark, as well as to be not in the dark not in the dark, but there are so many secrets in the world that it is likely that you are always in the dark about one thing or another, whether you are in the dark in the dark or in the dark not in the dark, although the sun can go down so quickly that you may be in the dark about being in the dark in the dark, only to look around and find yourself no longer in the dark about being in the dark in the dark, but in the dark in the dark nonetheless, not only because of the dark, but because of the ballerinas in the dark, who are not in the dark about the dark, but also not in the dark about the locked cabinet, and you may be in the dark about the ballerinas digging up the locked cabinet in the dark, even though you are no longer in the dark about being in the dark, and so you are in fact in the dark about being in the dark, even though you are not in the dark about being in the dark, and so you may fall into the hole that the ballerinas have dug, which is dark, in the dark, and in the park.”
