Lies........

Sometimes people try to hide others lies and mistakes and give excuses on their behalf.Since childhood I kept on hearing from people that hiding a mistake encourages more mistakes to be committed.Then why do people try to cover the flaws?Are they afraid that if they make others aware of the flaws they would go against them and love them less?If thats the case then could we call that true love?maybe love was never around the corner and they were seeking to catch a glimpse of a swift sensation...who knows???
