Laugh all you want, BUT anger consumes a person. The greater the effect what was done to him/her the longer the feelings will burn inside them. The most outwardly cheerful person could one day do something to another person that is SO, SO, SO out of character that people can’t believe what they just saw/heard. With a little background information, it all comes clear that the person was harboring so much pain and anger inside against the other person.
Anger management is good to an certain extent. BUT, anger management doesn’t remove the feelings all it does is mask them. If you harmed someone, it’s best to try to make it up to them while you still have a chance. Hurt people don’t forget what was done to them nor the one who did it.
