Honestly, I can make a lot of excuses for why I have so much stuff. Listing off a few off the top of my head are: my controlling mother brings things in and takes things out on a whim, I get miscellaneous gifts from friends and family that I don't always want or need, I'm sentimental, I never know when I need it— I got a lot of stuff ok? But, willing or not, it's still mine. That means, most of it is my responsibility if I want to keep my room managed.
