Gambling should never make you cry unless you win a huge amount of money and you cry because you are happy then you are allowed to.
But you should never cry if you lose with gambling because you should just accept that fact and move on.
I think the first point will never come in my life. Because I don't have hope that I can win huge amount in gambling. And it is not possible also. The second point yes we have to accept our loss. Because we know we are doing the wrong thing to make money so if lose our bet we have to accept that. But I think no one will cry until and unless he lose huge money in a single bet.
