Different people have different personalities and they have different ways of handling things.
A person may change due to something that might have happened in the past. We may judge, but are we judging from the truth or something that we think it's the truth?
People might use happiness to hide their sadness with a smile. But how many people are there that are able to look behind that smile? Over time, it become a emotional problem, causing the person to change... In their attitude to others. But what is exactly the right approach to our problems when we face them? Is voicing out really the way to deal with it? Sometime, it may not be. The person we voice out to may also have another opinion and starts another wave of unhappiness, frustration and anger.
It may not be that, but at least we have tried?
Even though we may not be fully satisfied with whatever ending there may be, but we should at least pat our backs and tell ourselves that we have done something that we should have done. We did it for ourselves!
But still we may not feel better? The scar with still be present. Time may be the only medicine or some other human will get in the way and speed up the long recovery path. I hope everyone will be able to find that one person.
