A lot of my time recently has been occupied by noticing annoying things that my flatmates do. Most of my flatmates are new so there is some things I have to get used to. I’ve found non-conflict communication to be quite an issue; I believe that personality clashes are real.
But there are commonsensical things that you would just assume adults know, such as: if you put a glass at the edge of the table, it is bound to fall one day. And maybe cut somebody’s foot open. Who knows.
If that’s what you want for someone you live with, then I wish you can live alone for the rest of your life.
