sometimes gambling is very good in our life as a gambling person, but the lesson gives me in my life in playing gambling games is not to spend all your money in playing because if all the money you have lose in gambling like me i lose the money for my electric bill then they cut our electric, funny but that is true, and from now on i will not bring all the money that i have in playing games, and become smarter in gambling.
