Bri - I just had a thought.... tape up racy (but not entirely nude) posters of Carmen Electra & Pamela Anderson in your windows (facing outwards of course). If she's a prudish old bat then it just might make her knock it off.
If you are lucky she will stop looking out her windows all together!
If you are un-lucky, she will be knocking on your door with a big smile. Eeewww...
