sounds like you need to invest in a beefy sub for a home cinema system.... doesn't have to be loud....but she'll feel it xD haha
had a similar sounding neighbour when I was in university, she lived slap bang in the middle of the "student area" but would forever be complaining about one thing or another!
started when in the height of summer we had a BBQ in our garden in the early evening, next day she complained her house stank of smoke and so did her freshly washed clothes because she left her window open and it was very inconsiderate of us...uhh....ok... sorry about your clothes but what you expect us to do
then it was always complaining about noise levels at any time during the day, we'd try and keep it down when outside later in the evening but ya know...we're students, we drank and had people over and it would get dark really late so we were making the most of it.
my housemate got given an asbo because of her...to be fair....he did deserve it but still
after a Joe Calzaghe fight and he was announced winner my mate lept up, booted a vodka bottle across the room and ran outside screaming and cheering. I was drunk in town at the time but he was out there at about 4am or something and she opened her window to tell him to be quite and he just lay into her with insults.... not his finest hour! I got home about 6am to a living room full of broken glass and drunk people being loud.. I went to sleep. I was woken up god damn early by her knocking the front door.. I answered and she was all high and mighty being like "hello, good morning, I expect you know why I'm here" I was like "uhhh..... um...... not really... can I help you?" then she got really sarky and patronising stating "ohh well ofcourse you would have any idea why I'm here.... you only live in the house and know what your friend did" I just told her I've not long got in and it's nothing to do with me and I'm going back to bed. and that was that haha! mate obv got an asbo....silly mug haha!
