Cathy's lies were never innocent. Their purpose was to escape punishment, or work, or responsibility, and they were used for profit. Most liars are tripped up either because they forget what they have told or because the lie is suddenly faced with an incontrovertible truth. But Cathy did not forget her lies, and she developed the most effective method of lying. She stayed close enough to the truth so that one could never be sure. She knew two other methods also -- either to interlard her lies with truth or to tell a truth as though it were a lie. If one is accused of a lie and it turns out to be the truth, there is a backlog that will last a long time and protect a number of untruths.
99% of all addicts are liars and thieves. This might sound unfair and even close-minded, but it's the truth. There are some exceptions to the rules, but they are incredibly rare. Most people are no match for their addictions. They will be driven to do things they would normally never have considered all in the name of getting high. Sad, but true. So if you're thinking of trying drugs, keep in mind that all the people you will be dealing with are likely to steal from you and lie to you at your own expense.
Don't lies eventually lead to the truth? And don't all my stories, true or false, tend toward the same conclusion? Don't they all have the same meaning? So what does it matter whether they are true or false if, in both cases, they are significant of what I have been and what I am? Sometimes it is easier to see clearly into the liar than into the man who tells the truth. Truth, like light, blinds. Falsehood, on the contrary, is a beautiful twilight that enhances every object.
