Is saying sorry really easy??

Is saying sorry to a person is so easy as people say it to be?Many times people just don't give importance to this words because they want something more than words.I don't think sorry is an easy word, it needs a lot of courage deep down in your heart.If it were so easy i would have said it to one of my mates a long ago.People generally say that u did all those non-sense and then just wrapped that up saying "sorry".Many times people misuse it but when it comes to a serious matter who dares to say even a word; saying sorry is beyond their skills that time.Hope i succeeded in giving my message properly to those who matters and also to those who are reading this post.
The last words "Don't repeat your mistakes to misuse SORRY; at the same time have a courage to say SORRY because a word can save you relationship"
