"When a deep injury is done us, we never recover until we forgive" Alan Paton

What this quote means is that in order to continue and live a happy life you must forgive what others have done.When you done forgive others you store anger only turning you in to a grouchy person with low temper.An example would be you and your brother, when you two were little you guys might have fought for a toy and haven't forgiven each other.Years have past and you still haven't forgiven each other but now the hatred has grown and worst of all you two have forgotten what started all this.If you were to forgive him he would too and it would be a new start.
