Philosophy of Sorry

We often say sorry even for tiny mistakes. Sorry is generally used for two reasons. Either by bad habit or to overcome the bad habit. I have seen many who commit the same mistake repeatedly and utter the same sorry after each mistake. I would say, their sorry is useless, rather a bad habit.
If you are really sorry, you would not dare to commit that same mistake second time. In Islam also, Almighty, Allah, the most Forgiver, forgives all his Ummah who beg pardon, do Tawbah even after committing dreadful sin. But if you commit that sin again, your Tawbah(sorry) is futile, your sin will be multiplied.
So be careful about your sorry.
