I live next to a facility that, from the best I can tell, employs mentally challenged adults. They get dropped off and picked up by social workers in big vans, and during the days they often cavort outside. I’m glad these services exist for everyone involved. However, they make a lot of unusual sounds bordering on cacophony, like someone is being beaten or interrogated and often they make what, no exaggeration sounds exactly like movie zombie noises. I naturally find it mildly strange but don’t think too much of it given the circumstances.
I also play really loud guitar and make all kinds of other noise from my studio, and it occurred to me one day all those people can probably hear everything I do when they’re outside doing their thing, and who knows what really loud guitar or deep bass sounds like to them. They probably think I’m pretty weird.
