OH BOY do I remember my neighbors like that - I had one that actually pounded her walls during my boyfriend's and my alone time - she was SO OBNOXIOUS and one day even came over and knocked on my door - I was so embarrassed - but we didn't handle it too well - that just made us noisier.
We almost broke certain furniture in my house trying to REALLY annoy her if you get my drift.....
Ahhhh...the good ol days....
I agree with Elizabeth - Kill her with Kindness - maybe she'll leave you alone ?
