Informality is displayed in the general way we behave, and , more specifically, in our language, and in how we dress. There is a proper place for informal behavior, such as when we are among family and friends. Here we can relax, need not “stand on ceremony.” But when we deal with humanity at large, when we are in the public arena, we should behave formally toward others. Why? The principal reason is that this is the best, most effective way we can show them the respect that is owing to them. Now, mind you, formal behavior does not mean cold, stiff, off-putting behavior. Far from it. Formal behavior is fully compatible with a warm, friendly, outgoing demeanor. Formal behavior, at its best, should be considered as a type of politeness, an expression of common courtesy.
