A bad apple might spoil that barrel of apples. But it cannot ever destroy all apples in all barrels everywehre forever.
A fleeting thing...governing. You're in you're out and life goes on. Everyone and everything is replaceable.
One bad experience does not mean it will always be that way. You hold on until things are better. MAYBE you can help make them better but at least you can cheer for the good guys and hope they succeed.
Do you?
