If I speak the truth - he acts like hes gonna beat people
up.
When I show my discontent by being myself (by not talking much to
him or greet him) - he goes to my school to spread lies to my form
teacher, and then when the discipline master starts investigating
further, there is nothing much to be done.
When I successfully pwn him with words, he starts talking nonsense
and walks away like he wins. Confuse people when you yourself are
confused.
