It is unfortunate that instead of appreciating a conscience move by a thoughtful reader you're criticizing it. If there is a mistake then it has to be corrected. If we dont show such carefulness then our nation can never become a world leader. Its always these small things that make the big difference.You have to be a perfectionist in whatever you're doing no matter who "small" the task is. Kudos to abcd for showing such high levels of carefulness. Hai-hai to Vinay Gupta for showing such ignorance.
