If a stranger came up to you on the street and called you a book, would it ruin your day? Probably not.
What if a friend called you a book? Would THAT ruin your day? Probably not.
Would the fact that someone called you a book actually make you a book? Unless that person is a wizard, then no.
So now that we are both certain that you know you are not a book, if someone did call you a book, would you feel the need to go to great lengths to “defend your honor” by explaining to that person — and others — why you are, in fact, not a book? Probably not.
If this isn’t beginning to sink in yet, just realize that I’m using the word “book” (which you know you are not), but it could be any other word.
So the next time someone decides to label you as something you know you are not, think “I am not a book”, and then react (or don’t react) accordingly.
I mean, if you’re not a book, you’re not a book.
