Lie if you must, but only when, you want to save the truth from pain

Why do people lie? Are they afraid of telling the truth? I meet many people who will just lie when it is not even necessary. I hate telling lies and will not lie even to save face. I tell my friends you can swear on my honesty. I go for shopping with my friends and they shop like crazy. But they go home and hide the stuff. They will not show their spouse what they have shopped. Some of them will not tell the actual price of their loot. Imagine buying a branded bag of fifteen thousand rupees and quoting a price of two hundred rupees to their inquiring husband, even though they bought it from their own saving. They will wash their new clothes to make them look old. They will scratch the price tag and pretend that they bought it on sale. They justify their action by saying that they don’t like unnecessary taunting of their spouse. Some of them pretend to be too much concerned. Every time you call them they will say that they have been so much worried about you and have been trying to call you and inquire about our well being, when in reality they have not even bothered at all. With mobile phone, telling lies is become even more popular. They will be dining in a fancy restaurant with their friends but will say that they are eating dhal-chawal and are very lonely. The fact is that truths is always out and imagine the embarrassment. The person learns to distrust you. The satisfaction of fooling others is always short lived because the guilt feeling is very sticky. I shall never be able to risk that!
