It was more like half hour because of waiting between texts and calls, not sure if waiting or not is less worse! I get that people aren't always tied to their phones. Or as you say, make a racket later, which I've had to do before, though not so early, which is the point, that I don't want to anymore. Did not tell neighbor preemptively because I hadn't seen them doing it, clearly we aren't on regular interacting terms for me to mention it out of the blue. They changed the "arrangement" to assuming it's fine rather than ask (my silence being complicit).

I suspect that in a separate conversation at another time, they still would have gone on, though maybe less explosively, about how I should be okay with them not doing it much when it doesn't usually inconvenience me anyway - exactly the kind of reasoning that works on a pushover.
