I Hate My Mom More than Anything Else in the World.

Okay, so here's the deal.
After we buy me the usual crappy thrift store costume, as my mom is hella cheap, she tells me that this will be my last year of trick or treating. I hadn't really paid attention to what I had gotten, thinking that I'd just get a better costume next year, but now wanted to think it through a bit more. But guess what? No returns at a thrift store. My mom is making me pay for it all.
And now, I don't even get to go trick or treating at all.
I was going to go with Lily and her friend Garrett, at his house, but at 9 last night, my mom realizes that she doesn't know Garrett's family, and has to meet them first. So she decides that Lily has to come home with me, we have to wait until she gets home, and she has to call Garrett. BUT, Lily decided to invite someone else, who was going home with Lily, so I couldn't go. I know I shouldn't, but I feel replaced.
So, Katrina was thinking about tagging along with us, so I had to call her and say that I couldn't go. She said she was going with Ripley, and that I could come. So we plan out a costume for me, and get everything all set up. My mom gets home, and I tell her my change of plan. She says okay.
I apologize to her 15 minutes before Rina was supposed to pick me up, for wearing a sleeveless shirt to school today. She wouldn't drive us to the high school, even though it was pouring, so I had to bike, and my other shirt got all muddy.
She got mad because there was a five minute period today that I didn't have my sweatshirt on, and said that I was "at school to learn, not to attract boys." Because, of course, I always get wet and muddy first thing in the morning so I can wear a shirt that I practically freeze in, in the hopes that some guy might look at me. When I tell her I wasn't wearing it to attract boys, she says I was giving her attitude, and says that I can't go trick of treating--OR camping with a friend. So, ten minutes before we were meeting, I have to cancel. And she won't talk to me about it.
So, basically, I hate today. I'm wet, muddy, and grounded. Someone please kill me.
