How can I quickly motivate my 10 year old sister to clean up her room, do her

[Cassidy]

chores, and finish her homework? Every afternoon I meet my 10-year-old sister at her school (with my 7 month old sister in a stroller and the dogs on a leash) and we take our time walking home because she enjoys it. She's already gotten to tell me about her day, play with the dogs, and stop at a store where I got her a healthy snack. I even let her go online when she gets home. I'm hardly running a boot camp or being unfair. It's been an hour and 20 minutes since school got out. Now I need her to clean up her room, finish her chores, and get her homework done, but I haven't been able to do any of that. I turned the TV off and she turned it back on. I unplugged the computer and she plugged it back in. My dad is working on a project in Malaysia at the moment, and my mom is still at her volunteer job at the church. When my mom gets home she'll be angry at me if the house is messy and my sister hasn't done her homework even though I've done my best to make her be good. I go to school online and am about to Skype with my partner on a project to work it out and I can't deal with the 10 year old. I've got the baby sleeping next to me right now, and if my other sister wakes her up with her noise it's going to be almost impossible to concentrate. I'm really too tired to deal with this, and as soon as I'm done Skyping I have to make dinner and do more laundry. My sister hasn't even taken her laundry I did this morning upstairs. I really don't think asking a 10 year old to carry her own weight is unfair. Is it? How do I make her do what she's supposed to do without having a big fight over it? She's not normally a brat. There's a complicated situation between me and my mom, and my sister is just taking advantage of it and using it as an excuse to be lazy and get away with things she usually couldn't.
