Thanks for the vibes and the commiseration. I've now had THREE talks with the building manager today, who must be as fed-up as I am with my neighbors. At last I feel we are on the same page. In the past, she just told me to talk to them myself. I did so, but it did no good. Now I think she's ready to evict. It's taken so much of my time and energy--and much of hers, as well.
