I live at home with my mom. There are some things I like about it, and some things I don't.
Living at home, rent-free has put me in a much better position financially then I would be if I was living by myself or with roommates - I'm able to pay my car insurance and phone bill, pay for school, and put money into savings instead of spending it all on rent and utilities. The dogs get much more attention and exercise, too - we're both out of the house about 40 hours a week, but we often work opposite days or overlapping times, so they're not home alone for 9-10 hours a day, five days a week like they would be if I lived alone.
However, there are things I absolutely don't like. I very much need my alone time, and its hard to get that when there's another person in the house that constantly wants to talk to you. I'm naturally very neat and organized, she's naturally very cluttered, so I feel like I'm constantly cleaning as messes are made in front of me. There are certain areas of the house that I've given up on (like the kitchen table, and the spare bedroom), because I'll clean them, and they're messy within 24 hours. It's extremely frustrating. She also insists that I'm quiet when she's sleeping in the evening(understandable), but she has no problem blasting the TV or the radio when I'm sleeping in the morning.
I will be continuing to live there until I'm done with college and can afford somewhere to live on my own.
