moving on...

Hurting people often hurt other people as a result of their own pains. If somebody is rude and inconsiderate, you can almost be certain that they have some unresolved issues inside. They have some major problems, anger, resentment, or some heartaches they are trying to cope with or overcome. The last thing they need is for you to make matters worse by responding angrily...So, keep your cool!

Also, a lesson without pain is meaningless  simply because no one can gain without sacrificing something. But by enduring that pain and overcoming it, he shall obtain a powerful, unmatched heart. A tough heart.

Lastly, the past does not haunt us. We haunt the past because we allow our minds to focus in such direction. We open memories and examine them. We re-experience emotions we felt during the painful events we experienced because we are recalling them in as much detail as we can. So, try to get over with the past and move on...
