I find it increasingly hard to forgive a person who keeps on being obnoxious. So, what can I do?
A key here is to first forgive from your heart so that you can approach the person without a lot of anger inside of you. Then try to have a civil conversation with the person so that there is opportunity for insight and change. A key here is for the other to change. Your forgiveness can play a part in that, but even if it does not, you will be free from the inner resentment that can compromise you if you forgive.
