Partners in crime

Good, you didn't have a choice anyway. You always have to agree with me. Now, in the movies they make killing people look very easy. I believe it is. All you have to do is figure out how, where, why, and when - no biggie. I had such a hard day today. The principal started yelling at me for no reason whatsoever. I was waiting in line for pudding, and she goes.
"Kid, where's ya money?"
"What do you mean 'where's my money' since when do I pay for lunch?"
"You have to pay for lunch, it's a rule"
"No body tells me what to do"
"Really, you really think so?"
Then I punched her in the face, cause why not. She went to go get the principal and then we got into a big fight. Now I am suspended for a week. But seriously, I still don't see what I did wrong. But anyway now I don't now how I will go to the movies. I guess I can just wait for her after school. I have to sleep now we have two days before the big day, I need sleep. But when I go to sleep think about how I should kill her. Meaning what should I use.
