I'll try to be brief. Her habit is to stay up until 1-2 AM, then sleep until 10 AM. During the day, she watches Law & Order, CSI, and reality TV. We switch off kitchen cleaning weekly; we routinely come home to find the kitchen hasn't been cleaned and she's left for work. A general habit of being as lazy as possible around the house, and when confronted, she'll either lie or start yelling, if forced to do something, slam and bang things around in the process.
As for the car, she got a speeding ticket doing 83 in a 65 before summer. Came home, complained why did she get a ticket, Dad and I are the big speeders, was pissed when she got scolded for it. She ended up getting lucky, and the cops somehow lost the paperwork. At that point, she took that as a "speeding isn't a problem".
Then several days ago, she cut somebody off, got clipped. Blames a bad intersection (it isn't), blames sunlight (wtf), claims they had a directional on (lol), and said 6" would've been enough to avoid the accident (try 2', from the marks on the car). So now insurance will go up, or pay out of pocket, either way, the parents are going to end up paying that for her, because she just goes out shopping and spending all her money.
That was as brief as I could make it. I'm annoyed, it's not fair to my parents at all, it's not even fair to me, everybody is miserable with this, and she's planning to come home to live here for 4-5 years.
