A liar should have a good memory.
The quote "A liar should have a good memory" suggests that those who deceive others must be able to remember the falsehoods they tell in order to maintain their lies and avoid being caught. It highlights the idea that lying requires a significant mental effort to keep track of the details and inconsistencies of the lies, as any discrepancy can reveal the truth. It underscores the complexity and burden of dishonesty, implying that liars often have to work harder to keep up the facade than if they were simply honest.
