The word "sorry" is a very powerful that has taken love ones, friends and family far apart from each other simply because they find very difficult to say " I am sorry " and this has also brought people back together because they find it very easy to say " I am or we are sorry" Yes, it is enough to forgive a wrong especially if is said with a sincere intention. Personally I find it very difficult to say I am sorry for an offence I know I didn't commit or for misunderstanding I know I am not at fault but honestly if I am convinced that I at fault I find it very easy to say I am sorry and I say that wholeheartedly. It is a very expensive word for people who have self respect and are always responsible for their actions, when they say it they sincerely mean it so it highly worth it for a wrong doing.
