SeriousOne, there is a white noise machine in the baby's room-- that's a testament to how loud the screaming was. When my husband came home and took a shower I went in to tell him that I thought I pissed the neighbor off and why. While in the shower with the water running he said, "I thought I heard screaming."
Peanut22, this neighbor used to bring us dinner (because of being a new mom) a few times a week. Now when I say hello she doesn't even turn around, just walks off while waving over her head. No doubt she's done being friendly.
Thanks for all of your answers!
