Evil sister

My sister is a evil little brat about 95% of the time. She is always trying to find a way to either make me do her work, get me in trouble, or make what I am doing many times harder to do. She has never heard of actually helping someone, much preferring to come up with about 50 excuses for why she can't, or won't help. She always has something else she needs to do, or she can't help, or quite often she simply doesn't feel like it. She loves the clock, often looking at it every 50 seconds or so, and she has a great big tantrum if she gets even 5 minutes late.
She views it as her duty to make absolutely sure that I do everything that I'm supposed to do exactly when I'm supposed to do it exactly how she thinks it's supposed to be done. Often it's like this:
Evil Brat: "Have you played your music?"
Me: "I--"
Evil Brat: "You haven't."
Me: "How do you know?"
Evil Brat: "Mom! Mom! Jason hasn't played his music!"
Mom: "Jason, go play your music, now."
Evil Brat: "Mom! Jason's getting up off the piano bench!"
Me: "I am not."
Evil Brat: "Mom! Jason's getting up again!"
Me: "Shut up."
Evil Brat: "Mom! Mom! Jason called me a name! And he's up again!"
Evil Brat: "Mom! Jason isn't playing his next song."
Evil Brat: "Mom! Jason is tipping the piano bench."
Evil Brat: "Mom! Jason got up again!"

She also thinks that whenever she doesn't feel like doing something, all she needs to do is not do it and I will end up having to do it. Often, after I have closed the gate to the goose pen for the night, she decides that she wants to go in the goose pen. She opens the gate, goes in the goose pen, comes back out, and heads off to do something else.
"Keely, please close the gate."
"I don't feel like it. The geese can just roam around outside tonight."
Obviously I have to go back outside and close the gate myself. Yesterday we were doing the morning chores. Keely looks at her watch. She walks over to dad.
"I'm out of time, may I go in?"
Then she zips off into the house. This is what I have left to do:

• Milk one of the goats.
  
• Get the goat bowls out of the buck pen.
• Put grain in the goat bowls for the doelings and 2 bucklings.
• Put hay pellets in each bowl.
• Take the bowls over to the goat pen and set them out.
• Get the leashes ready to tie the goats up with.
• Let the 2 bucklings out of the doeling pen so they can eat.
• Tie the 2 bucklings up.
• Let the little doeling out so she can eat from her bowl outside.
• Go into the pen and give the rest of the doelings their food bowls.
• Tie up the doelings in the pen so they don't steal each other's food.
• Tie up the small doeling outside.
• Go get the hair brushes and brush the 2 bucklings.
• Brush the doelings.
• Put the brush away.
• Wait for the doelings to finish eating.
• Go around and collect the empty food bowls.
• Untie the doelings.
• Untie the 2 bucklings and put them back in the doeling pen.
• Collect the leashes and bowls and take them over to the milk parlor.
• Hang up the leashes on the wall.
• Wash out the goat bowls.
• Dump the dirty water out of all of the water containers in the goose pen.
• Fill up the water containers with fresh water.
• Get the 2 geese that are over by the goat barn.
• Feed the geese.
• Turn off the water and put the ramp for the goslings into the big water container.
• Let the 2 crazy drake ducks out of their cage for the day.
• Ask dad if I may go in.

Keely should have helped with feeding all the goats and with taking care of the geese. This should have taken at the max 30 minutes. Instead it took an hour and a half. When I got in I had about an hour of math, 45 minutes of music practice, and 2 hours of writing left to do before we left for our photo shoot/sketching trip and then for our music lessons. Keely was over half done with her writing. When I finished math she was ready to start the sketching trip. I went to play my music and dad gave her a book to read for part of her sketching subject. When I finished my music Keely only had 3 hours of time left and was ready to leave. We left. When we got back from town it was 6:00, time for chores. It was bedtime when we finished chores.
Now, today, I have close to 2 hours of writing and 50 minutes of boring reading to do. There is not supposed to be any school today. Evil Mrs. Keely is loafing around the house, playing, messing around with her computer, and trying her best to distract me with loud noises and to read this post over my shoulder. AAAAARRRRRRGGGGGG!!!!!! CURSED, BRATTY, EVIL LITTLE GIRL.
