"True friendship is like sound health. The value of it is seldom known until it is lost," Charles Caleb Colton said. Just like in any other relationship, arguments and fights are also part of friendship. You will hardly find friends who have never fought with one another. Whatever the reason is, if a person feels that he is responsible for causing the differences, it is important that he should apologize to his friend.
Though you can use the email, text messages or chat for expressing your apology, the good old way of saying sorry to your friend through a letter will surely have a great effect on him. This will make your friend realize that your efforts of saying sorry are genuine and that you really care about him.
Points to Remember:
Timing: Write the letter at the proper time. It is not advisable to put it off for too long.
Words: While you are writing the letter, what matters most is that you truly feel sorry.
Sequence: Always begin by apologizing and saying sorry for your mistake. Then explain to him your side of the story. In the third and last paragraph, talk about what his friendship means to you and make a promise of not repeating the mistake.
Delivery: You should either post the letter or deliver it personally or through someone else. You can also keep it at a location where your friend will be able to find it easily.
Some people may try to point out the friend's mistake while writing the letter. Avoid this completely, as it can make matters worse. The letter has to be brief and should only talk about the subject that has led to your apology. Keep patient and do not expect immediate results. In some cases, it may take time for the person to forgive and forget.
