I am against with your question we should not take revenge when we are wright or wrong when we fill we have to take revenge of a person then it totally destruct our mind and we don't concentration on our work and we have a negative aspects coming in our mind.

So,don't think of revenge instead of hurt him or don't talk with him or don't do anything which can make you to take revenge so always remain away from him and after some days you will totally forget him then why we should take revenge if we are right at a place think positive.
