Pretend - even if you only feel two inches high inside. Avoid being alone as much as you can. Whenever possible, travel with others to and from school and to special school events. Students must always be aware of their surroundings. Stick with a group, even if they are not your friends.
Bullies tend to pick on people when they are on their own.
It's especially important to try to avoid being alone in places where you know the bully is likely to pick on you. This might mean changing your route to school, or avoiding parts of the playground, or only using the washroom when other people are there. Practise what you want to say. Think up funny or clever replies in advance. Make a joke of it.
