Someone, someone

Why is so many people against that one person?
We are all classmates, so we should forgive and forget.
Nothing is definite; people can change.
But they need time. And they need the chance.
Hostility will do no good. We should forget the past and move on.
Give him a second chance, and let him start afresh.
Then we may see the good in him.
And gradually, bit by bit,
Change him for the better.

Everyone would have erred before,
and others have given us a chance.
So why don't we give this person,
a chance to start anew.
