My sister is complaining about a free place to sleep

My siblings and I did not have the best life when we were kids.

We were in and out of foster care for years.

Our dad went to prison when we were in elementary school, and Mom started doing drugs shortly after that happened. We had a rough childhood, but all three of us managed to graduate high school and find a good job. My sister is the baby of all three of us. She got married right after she graduated from high school. Now she has two kids and she is getting a divorce. When she decided to leave Bob, she came to stay in my condo. I wanted my sister to leave Bob for several years, so I was happy to help when she finally made the right decision. Unfortunately, it’s been a lot of aggravation since my sister moved in to my house. First, I am not used to hearing two small children run around the house at 6 in the morning. I am also having some trouble with the neighbors. They don’t like hearing kids running around at 6 either. My sister isn’t working right now, and she sits around the house all day doing nothing but watching tv and eating ice cream. The worst part is the fact that my sister has been changing the temperature on my thermostat. I like the thermostat at 72 degrees. It stays cool in the house and I don’t have a large bill at the end of the month. My sister has been adjusting the thermostat to 68 degrees during the day. I haven’t charged my sister anything to live in my condo, but her lack of respect for my home and my thermostat is starting to get on my nerves.
