The power of the words is an art, a fine art that can only be learned over time. Different words can only be used with certain people, judgement and when the line is far enough, come into play. some people get offended by some peoples words whereas others use the same words on a daily basis. Different situations bring out the differences in you and your manor, the words we choose for our parents are not the same as our choices for our friends.
Thats what makes us individuals, Differences.
