Okay, so this is a weird one but I'm not sure what to do. We had some new neighbours move in a few weeks ago to a rented house next door. They have been generally unfriendly when we see them on the street, not saying hello back, etc.. That doesn't bother me. But yesterday, a man (not sure if he lives there) chanted in their garden for about two hours. He was standing facing the garden wall, reading from a book. It sounded religious, saying things about burning in hell, your soul perishing. I couldn't have made this up!
It finally stopped. But then a dinner party started in their garden in the evening. I usually don't mind the chattering of voices, but they were really, really loud. I think there were some passionate discussions in Russian going on. At about 10pm, I went out in my garden and asked them nicely (over the garden wall) if they could talk in normal voices as I have a DD in bed who is 2. They did generally quieten down, but stayed outside until after 1am having their party. On a Wednesday night....
So I am now paranoid that some really inconsiderate (and probably nutty) neighbours have moved in next door. Would you risk writing them a note or wait to see if something else happens?
