<human>: My roommate [22f] of 2 weeks is new to town, I [32f] have lived here a while. How much interaction do I owe my roommate? We live pretty separate lives. She leaves before me in the morning (before 8) and returns home after me (after 8). Since I don't want to be "dressed" all the time (wear a bra, shave my legs) and want to wear only my nightdress, I tend to stay in my room with my door closed. We hardly talk, and go for days without talking. 

What do I owe my roommate, apart from paying rent on time and keeping the common areas clean? Should I greet her when she comes back from work? Should I go and sit down with her and talk to her when she eats dinner by herself in the kitchen (I usually already have had dinner by then)? I have had problems with roommates in the past and I think maintaining some distance is good, a roommate relationship is essentially a business relationship, not an instant friendship, However I keep feeling I am ignoring her and she might be lonely and she is seeking out other friends and hanging out with them because I don't offer her any companionship.

Can you summarize the given text in a few sentences?
<bot>: What does a good roommate relationship look like, other than paying rent on time and keeping the common areas clean? Do I owe my roommate companionship? Is it rude if I stay in my room and ignore my roommate?
