No, thats not polite. Keep yourself busy in something else. You have a lot of options.

change your place and do something you love to do.

Yeah, go for it!!!!

there's nothing good to gain from fighting. you'll both end up losers. However, this is just my personal opinion as I am not used to fight unless the issue involves my family... I mean, I only fight back when they hurt my family. :)

to good players who answer this question, lets say i am the oppsite side for a while,i think fighting is not just a answer but sometimes we need to do that to show them that we are not weak,cause everytime we are we keep on walking away or just to be quiet they just continue bullying you every where,but once you show them your capable to fight back they will leave you alone. we all knows the rule of "mights make right" we need to show it was wrong by striking back. or you can fight back using words like what they say "who need action when got words" cowboy...
