Why is it?

Ever realize how "Why is it" questions never really have a real answer. Merely just a thought from one person to another. I guess it is generally because most "why is it" questions are questions from the heart, and not typically fact finding questions. (Though it would be easy to ask a fact in that sort of way)

My "Why is it?" question of the day: Why is that when you do something that you feel is right for you, that it is not generally the best for others effected by it?"
