Simple sorry is enough to put off disputes if meant truly but not many are willing to do that as they hold onto their ego.
Do you find it hard to apologize?
At time I may be strong head if I know that I didn't do wrong the person but whether we are right or wrong we should learn to apologize as two wrong can't make right.
Two wrongs can not make one right truly and also sometimes we don’t apologize because we are wrong,we apologize in order not to loose our relationships with people.
