Liar should have a good memory.Lieing is not an uncommon thing. Many people lie time to time to circumvent the present situation or embarrassing queries.
Though, lieing is considered as a clever and bad attribute in the society but sometimes it saves people from embarrassment and inconveniences of facing the other people and getting exposed.
Though with time, these things are known to others that a person had lied but the lier gets an advantage temporarily.
Sometimes the liar is caught at the spot because he can not answer all the questions properly. So, it is said that the liar should have a good memory and he should remember all earlier questions and should tell his explanations accordingly.
What is your take on that?
