If you are a person who recovered from being hurt and have lashed out at everyone else because you are hurting, then you must have realized by now how easy it is to hurt others when you are hurting.
When you lash out, you feel like you can always be excused just because you are hurting.
If you are on the receiving end, it might take you aback.
Sometimes, a mind not ready for a confrontation protects the body by responding with an equal measure of counterattack.
Only when the emotions subside will you realize you could have controlled your impulses and resisted the urge to strike back.
