Roommates

So I've begun to realize that my one roommate expects me to talk to her all the time now that I'm home from break, the only problem is that I don't always feel like being sociable. In fact I've gotten use to being anti-social over the break well talking to my cousin and aunt the exception. All that aside though I don't care if I talk to people all the time, I am perfectly content to sit at my computer, run errands, or work. What gets me the most is that now that she can't use her computer she expects me not to use mine when if she could use her computer she would be on it just as much as I am on mine. Besides I have been talking to her and I play games with her all the time, its not like I am completely ignoring her or what not I just felt like being on my computer.
