I have an annoying neighbor who sings Sonny and Cher's songs rather badly. She's loud and has a voice like Roseanne. Oh, also she is naturally loud and her voice carries pretty far. I don't hear her too much anymore. I think I've learned to ignore her like a background noise. One of my daughters friend recently asked "Who is that? "and we were all like "What?" Oh it's Mrs. K. She is probably nearing 70.
When we first moved in. I tried to be nicer to her, but she is truly a "mean" person. She can be nice, but I really don't do well with "mean" people. She always has something nasty to vent about someone, at least in my past encounters, which since I rarely talk to her now, maybe once a year or less isn't stressing me out.
