We have a lot of discussions about our homes and apartments here on Cyburbia. Well, I found a couple of threads about home improvements, others about household appliances, and then there was this thread, but I couldn't find one dealing with what I call "house quirks." These would be the odd little things you've discovered about the structure in which you live: building characteristics, bizarre improvements ("What were they thinking?!?) made by a prior owner, things that annoy you about your place of residence, etc.
I'll start with the random thought that inspired me this morning: Why do we have three separate wall outlets in the walk-in closet in our bedroom?? Who plugs in multiple items in their closet, anyway?
I'm sure I'll come up with more as others post their house quirks (which I'm sure are far more interesting ).
