I just came across something.
People will never know what are you feeling inside because you don't want to tell it out due to some circumstances but you can't just judge a people by its cover. Some have to put up a tough look outside to cover up the fear inside. Maybe to prevent from unnecessary unhappiness in life, some have to defend him/herself by putting some hatred towards some stuffs. Can't blame that defensive method. Everyone has different ways of protecting him/herself. That's normal. Forgetting might be easy but forgiving is the hardest part of all.
