Man is a combination of two elements. A soul and a body. The soul wants honor. The body has a different agenda. The body isn't interested in wearing a suit, because it isn't interested in honor.
Honor implies responsibility.
If people see us as worthy of being honored we feel the responsibility of having to live up to their expectations. Responsibility isn't something which interests the body. The body wants the freedom to gratify itself without thinking about consequences. One reason is to give honor to this special day. But there's another reason.
