You should ALWAYS fight back no matter what, if the person or thing attacks you, you attack them back, you must have self defence just in case... I don’t know if it’s true but I heard this once that if you pass the same person 35 or 36 times, they may be the murderer (But it can’t be your family or your classmates) but always be prepared and make plan B or plan C or as many plans. One tip for self defence is that NEVER punch or kick the person with your feet, the person might catch your feet, and break your bones causing you in much pain that you will be in danger of that person.
If anyone ever says anything mean to you, just tell them the same thing they said but in another way or other things to say to mean people.
