The primary bathroom at home here, on the second floor, has an exhaust fan. This fan has developed a slight flaw recently. It's been there for over 20 years after all, so it might be understandable. On the other hand, now that it's far more effective at letting out a horrible screeching noise than airing out the bathroom I don't care what it's excuse is. Another unfortunate design element is that this fan is wired to the same switch as the primary light -- there aren't independent switches for each. Personally I've taken to using the night-light unless I absolutely need the extra light. It's hard to avoid using this one since it's the one that has an actual bathtub/shower (and the cats litter box occupies the downstairs room...)
My father took a look at it on his off day earlier this morning -- and well, it's still not fixed.
