<p>Hmm this is a very interesting thread. If I was the other roommate, I will contribute to it because to some extent, it is my fault that the door was open. You were doing me a favor and it costed you your laptop. However, you shouldn’t expect some money fron her because she clearly is irresponsible. My advice is to get another roommate who actually respects you because it is pretty clear that she doesnt.</p>
