There are four traits which differentiate people (in dealing with property):

• "What's yours is yours and what's mine is mine" - a mediocre person, and some say this characterized Sodom.
• "What's mine is yours and what's mine is yours" - a fool.
•  "What's yours is yours and what's mine is yours" - a righteous person.
• "What's yours is mine and what's mine is mine" - an evil person.
