It is a normal behavior when we loss something even we loss one penny, we are crying, if we are rich than it doesn't matter for us, but for the middle class person always cry when he lose and gambling always giving crying. i saw mostly people crying when they was playing gambling.
They must have lose a lot a lot to be crying. I have a friend who can lose $1000usd per night and the couple still can often go casino to gamble almost every month.
