Forgiveness Takes Strength

Someone who cannot apologize when they know they were in the wrong, has Problems.

And someone who will not accept another persons apologizes or attempts of making things up to them, is a Weak Person

And a person who cannot forget the past, but must dwell on it, discuss it regularly, hold grudges, is a Miserable Person. 

And everyone knows Misery loves company - so they will attempt to pull as many people into the conflict as possible. 

Those people who choose to be weak and miserable - there is nothing you can do about it. 

Some people are just pure evil and it would please them to see you beg and grovel. (Even knowing they aren't going to forgive you anyway, they just love the attention.)

Do not give in to these kind of selfish attention-seekers. 

If your attempts of apologizing and/or trying to make up doesn't work - then drop it. 

You (and others) will know that you were the strong one, and they were the weak one.
