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.
