Apologies

I saw Lage raho munnabhai a few days back...Gandhiji suggests munna that he shud apologize to jhanvi. Munna also does it the same way by writing an apology letter.
That particular rendition of apology triggered my thoughts, about effective ways of apologies. The various ways that I could think of saying those three words. " I am sorry " ranged from singing
Please forgive me, going down on your knees and chant Please forgive me at an express rate. you could leave a store bought sorry card. You could try making it up by being useful and a sudden interest in their mundane activities.
All these are extremely effective and would work 9 out of 10 times. There is one more which will work 10 out of 10 times. That is too look at the person straight in the eye, with a feeling of deepest remorse which is heart felt and say I am sorry I let you down. Even the coldest person in the world couldn't say no to that.Yes you might get punished after that, forgiveness is not returned instantly but yes, the person would have definitely started to forgive you.
