Do you suppose that the world revolves around you? Everyone does to some extent but it's also necessary to be considerate of others' feelings. People are people; we pass by many everyday, few good and few bad, yet they are people who can feel joy and pain. A person, no matter what he or she is to us, is not disposable. It's normal to be self-centered and do things if only it benefits us however it doesn't give us rights to use another person for our welfare and then cast them away without thinking twice. We might even remorse and want to compensate for our mistakes but some wounds can never be healed.
Sometimes apologies don't yield forgiveness because such would be our mistake; we quetch that the person, who is supposed to forgive us, is overreacting but we never wonder whether we would have forgiven if we were the one to bear that wound. We might have even sought revenge.
It's easy to ask someone to forget their bitter past; it's also easy for that someone to pretend to have forgotten that past but only he knows how much it hurts when he's alone. People forget everything but some things are hard to forget. With time, it might not hurt much but still it does hurt.
Not everyone are alike; betrayal might break someone completely, while others move on easily. If we belong to the latter group then we are lucky but the former have it hard on them. They are so sensitive that small things affect them greatly and though they wish otherwise, they cannot help it.
People die/kill in the name of love and everytime we hear of such people, we cannot help but chuckle. They seem silly but then we cannot judge them without knowing what it was to be in love for them. Love, like life, means differently to different people. Some people fall in love easily; for such people their day starts and ends with love. And we should be extremely careful when we deal with them. Our one mistake might shatter their hearts and dreams, and then only-god-knows-what.
Everyone needs a companion, who would stay by their side till the end; only saints seek solitude by choice. Trust is the base of every relationship and when we break someone's trust, they might crawl down into darkness and then do not trust another person again. What could have been a beautiful life otherwise, would become a lonely journey that they might never want to take. They exist alone but, forever, wishing differently. It's really cruel to play love with someone without telling them that it's just a game; they might take you for real and when that dream is broken, everything ends for them.
However, we are mere humans and are prone to make mistakes but we can surely consider others' feelings and the consequences of our actions before doing anything. If we intentionally hurt someone then we should be able to accept when somebody else plays the same game on us. Why do we complain then? We shouldn't curse the person who plays with our emotions, instead we should laugh at the joke played on us.
