If you are going to accuse someone of lying, you must consider the following:
   
       1. the facts in the case also known as the truth

       2. you must have an absolutely accurate quote from the person in question (hint: you cannot make-up one to suit your purposes)

       3. you must be able to tell intent to deceive as opposed to faulty memory or an accidental mistake in facts

(Hint: I hate Bush therefore he lied is not good enough for any rational person.)
