Look at it as that's life and then compare your life span to a piece of string. Tie a knot at about where you think you are on that string and say that's the day the lady laughed at you. Now look and see how much string you have left. You still have a long time left to worry about that silly lady and that little bitty knot. Next time just smile and walk on by. Don't wish her ill and don't make her day by letting it disturb you. Life's not worth getting your feelings hurt there's too much string left.
