think of evil way to get back.
u can start by calling him names, remind him of anything dat is
painful to him, insult his whole family once a while. critisise and
complain to him as much as possible. when he hui lan you, call him
a bad fren, and warn all your frens and make sure to spill any
secrets about him to everyone u know.
den when he come sgforums to whine, scold him.
