Don't be fool enough to think you can know a person's character after a few moments of observation. You have no idea where his life began or how his saga has unfolded thus far. Only his present state can you witness. To judge him at a glance is like reading one page in an open book, believing it's enough to confidently recite the story from beginning to end. True, one page may tell you much, but not nearly enough to accurately critique a book or evaluate a life. So, either become his friend and learn his entire story, or refrain from commenting on a tale you know nothing about.
