The Perfect Family???

What do alcoholism, adultery, gambling, overspending, excessive frugality, smoking, and pomposity have in common? They are all things of which my siblings and I have been guilty. Yes, the very same siblings who think they are too perfect, too blameless to hang out with their flawed sister. And just for the record, I plead guilty to gambling and overspending. Guess that leaves all the others for all the others.
