Everytime I hear the word gambling, risk comes next to my mind. It is either win or loss. Off course I feel happy and great when I won but naturally upset when I lost. I am willing to take the risk so I am aware and prepared on what my fate will be in gambling.
Indeed, I don't know why OP asked such question when the answer is too obvious.
Whoever it is, if he wins on gambling then of course expect that he is going to be happy, unless he is an insane person who would cry (not the tears of joy) even if he wins in gambling. I've tried gambling just once, and it is so good every time that I win on it, that is why I guess it is addicting.
And every time that I lose, I'm not just an upset one, I'm pissed, annoyed and so mad about this gambling site thinking that they are not fair(which is true, lol), so I've decided not to do it anymore.
