Guys, maybe I'm the rare one here, I have a very bad temper and low emotional stability!
Because I'm hot-headed and quick to anger, I may react emotionally when someone piss me off. It depends, if in Real World I tend to be more expressive when it's come to emotion because my motto is, "Do immediately what you want to do,". Expressive means I may scream at them and angry back to them, or react with all my sensitivity like crying in public.
If someone in internet piss me off and they're of course not in the same place as me, I tend to keep those to myself or pray in the bathroom. Or maybe, I listen to some musics to lighten my problems.
