WHY PEOPLE LIE???

• Some people lie deliberately but they think that their lie is harmless or even beneficial such as making a joke at somebody's expense-in the spirit of fun.
• other people lie because they think that since others lie anyway,they might as well have a head start. this is the ''if i do not lie my competitor will lie"fallacy.
• still other people lie because they believe they are entitled to make money out of their cleverness.
