When you have done something wrong, you will definitely have some regret when you realize that it’s a mistake. It is appropriate and taught you the new lessons from your mistakes. But when you haven't done any thing wrong and still you have regret than what do you call it?

Firstly when this question arises in your mind, you start scrutinizing that weather your perception is right or wrong. Many times, it happens that person or thing is so much important for you that you always neglect their mistakes. But when you need to show them the red eye for their mistakes, you will internally feel bad because of the feelings towards them.

Like parents do not want to get angry on child. But for the betterment of their children’s future and to keep away from the bad habits, many times they have to take this kind of stance. Actually, at that time they internally feel bad while getting angry on the children. Similarly happens with our friends and you really feel bad.
