Sister currently goes to University 5 hours away. Pretty much hates being so far away from everyone, and doesn't like living with people, avoids the other people in her house just because of that. So she's moving to one half an hour away, but doesn't drive, and doesn't want to live at home (picky picky), and will run into the same problem. Parents pretty much spoil her (my spoiling dried up when I got a full time job, I pay for a portion of food and majority of the internet bill, and have my own car etc, living rent free to save for a house but realistically the money that I would have put aside on rent gets spent on stuff I don't need) but are unwilling to pay for an entire apartment just for her. Mom and Sis proposed that we get an apartment together, and split the cost of rent. I'm not overtly against it, but would like some idea of difficulties that would be different than when we're both at home for extended periods of time.
We normally get along pretty well, when we're in a disagreement over something it's usually pointless shit that we get at each other's throats for but it drops just as quickly as it escalates, typical brother sister crap.
