What I achieved today: obtained landlady's written permission to replace the doorknob on my room with a key-entry doorknob, which technically is required by law anyway; then went and bought said doorknob ($80) and various necessities for installing it. Then I go downstairs to do laundry and I notice that Downstairs Roommate's door has a keyed-entry knob. So... Really? Like, why don't the rest of us have keyed entry on our doors? I mean, exclusive of the fact that it's required by law and should have been done before you advertised the rooms for rent? Sigh.
