I sent an email to the Massachusetts Consumer Affairs department, or whatever they're called, asking if, in my situation, I'd be considered a landlord. There are all sorts of legal things that go along with being a landlord (which I found on their site, which was very nice), so it might be a slight pain in the ass, but not as much of a pain in the ass as not being able to pay my mortgage.
Doing some laundry now. I finished Thomas Gray, Philosopher Cat, which I enjoyed a lot. Now I have to find a nonfiction book to read. I don't think Programming Perl would make good reading straight through. I think I might pick up one of the books on chaos or infinity that hrafn got me something like 3 or 4 years ago for Christmas.
I'll probably also do some dishes, make some food, and get my assignment done.
