Sometimes you just gotto look at things from the vibe perspective.
There were people having a fun time in the yard where I live. It was late around 1 am. They were enjoying themselves (good vibe), laughing but not about someone you could hear (meh vibe) like ridicule.
Then somebody shouted from a window and shut them up and it was quiet then, as if he casted a spell, I mean you could look at it like that. But it was no peaceful silence, rather a dead one, where there has just been something alive.
Now I wonder is it really about silence that you need to be able to sleep (better). Isn’t it more about something comforting which such vibe would be.
Now surely it may have confronted him with such vibe he doesn’t want to have cause it confronts him with something. But then which one is the more mature one. His shouting was based on fear effectively.
As for their reaction, surely if they’d kept it up he’d call the police and they don’t care bout that. But also how often do people change from their joyful vibe to the lower one finding themselves in an argument why they should have this fun time. Why leave the good vibe but is it really a question of choice or rather perception?
Then others may realize the fear in him and would ridicule him, which also makes them lose that vibe although this is rather typical for low vibe get togethers which you can hear by the way people laugh.
