What is the point me telling lies just to cover up my gambling track if being asked about such and besides it is my right to do whatever I feel is okay with me to multiply my source of income. So telling one a lie about your gambling loss just to cover up wouldn't help matters because you never can tell if the person could be the one to help you get back on your feet through advise or even teach you more gambling techniques that could be of help to you.
People lie just to feel among winner, but is a senseless thing to lie to your friend about a lost, its better you open up so you can get help. as human because do things that pleases them, and some times because of inferiority people lie to cover up. Whether you lie or not bookies does not care you money is gone.

But if a friend ask me about how my weekend gamble goes, i will them him exactly how the weekend goes without lying about it just to feel among. Those that lie about their loss just to feel special are deceiving themselves, because no one cares.
