The pool of votes are leading by the option, No, I hide my emotions if I lose or win, the majority falls under this category.
How about you what's your position?
If I let others know that I win, it won't be much except I volunterily inform you to enjoy some part of my winning, if I lose, I'll also do the same by sharing the news to those I truly wants to here too.
I do not over exaggerate when I win, I do not mood swing when I lose also, I keep the balance which is actually good for my mental health.
