I judge books by their covers
Why would you want to judge something based on appearances alone?
Why not judge books by their covers? Life's too short to waste time on learning about the personality of someone.
Physical appearance is easy to judge, but it is also superficial. Get to know the person and who they are first. You will be missing out on some really fine people if you don't.
So you are saying that if a person is ugly, I can't talk with them?
That is the opposite of what I am saying. Next time you see someone who is unattractive, strike up a conversation with them and you may be surprised with what you learn.
