Wanting more is the common mentality of every gambler. Before we risk, our inner mind used to have the thought to stop gambling once the bet is won. If the bet has won, then the gambler goes further looking for the win on the next bet. If the bet is lost, the gambler's mind starts to look for opportunities to recover what is being lost. This is common, and what we see is the incident between two friends. At the end we were able to understand that money can change one's mentality in no time. We need to be mature enough to handle situations in a positive way.
