Some reasons -
1. Some of us are sick or bed-bound due to illnesses which is correct.
2. Some of us live in multi-generational homes due to cultural reasons. So my parents live with me.
3. Some of us live all together b/c our parents lost their homes due to a financial crisis etc.
4. My home is more comfortable than a cold hotel. I prefer to be near my bedsheets and etc. I know it sounds stupid.
In my case, I've been dealing with depression, which my parent's dont understand and they're very overbearing so they check on me once in a while. My parents don't want me to die b/c I am their wage slave. I wouldn't have mind that - if my father wasn't as toxic but I don't have the heart to kick him out. I can't wait another 10-20 years till he croaks. He smokes like a chimney yet he won't go. I'm tired of him. He makes the most toxic comments on earth. I want the world to know my parents are the main reason why I'm ctb.
