When we observe our surrounding we come to know how many types of people and things are there in the world. If we see some other person doing something that we dislike, we are also likely to remove that habit from ourselves, because we know that how it feels to watch it from an other person's perspective. If we appreciate someone, we also try yo be like him or her in order to earn appreciation ourselves. To conclude all this, we know that where we stand in this big world.
