Ignoring
Ignoring can be really hard. But it's your choice to ignore or not. If you fight with them more and more then it will become a catastrophe and somebody mite get seriously hurt. If you really want to yell and scream try thinking about other thoughts or try to ignore in t'll the person that you are trying to ignore starts getting bored and goes away. If none of the ideas work you could make up your own way if you do not want to do that than you are out of luck.
