I want to cough and disrupt the game because I am angry
Do you think that this happens often?
I'm considering cough intentionally in the game because players annoy me.
It is expected people to cover their mouth when they cough to not spread germs. It is also wrong to try and distract players to ruin a game.
It's not like I'm cheating. It's just a cough.
You may not be cheating but it would still annoy other players and disrupt the game. That's still unfair.
