Again, this is not about you and your personal experience. You do not know what kind of day someone else has had, and when Slack has 25+ notifications and you have deadlines, little failures to be considerate DO take a toll, just like when someone honks their car horn at you for no reason or refuses to hold the elevator for you. Sure, it's not genocide, but it's inconsiderate. Just because littering isn't murder doesn't mean it's fine.
