You walk along minding your own business when all of a sudden a person starts verbally attacking you for no apparent reason other than to pick a fight with you. After they say their drivel, they ultimately push you down to the ground...
Now is the time to stand up for yourself and push them back, knowing full well its going to start a fight, but then again it might not be worth it and the smarter thing would be to walk away.
What do you do?
