Here is some advice to help you feel less intimidated by a bully and stop bullying.
First of all, you shouldn’t look weak. Bullies usually pick on such people. To avoid this, you shouldn’t look at the ground.
Second of all, you should avoid the bully. If by some chance you come across him/her, make sure to be with a friend. Bullies usually bother people when they see them by themselves, so by doing this, you have less chances of being bullied.
Third of all, you shouldn’t let the bully know that he/she is bothering you and don’t bring anything he/she requests. This will only encourage the bully to continue.
Finally, if everything else fails, you may use a mild insult. This may be effective because the bully isn’t expecting it. As a result, you will appear stronger to the bully.
