Mirrors have a purpose. We use them to get ready for work, for an evening out, to make sure clothes fit right, straighten up our hair a little, or just to make sure we don’t have cilantro stuck in our teeth after eating at a Mexican restaurant. When we take a moment to look into a mirror, it is to see a picture of ourselves and make necessary changes. It would be completely pointless to gaze into a mirror, notice our shirt is buttoned incorrectly, then just leave it and continue with our day. That would completely negate the purpose of the mirror.
