As a rule of thumb
Don’t assume you mean anything special to a person if they don’t show you and very confirm that’s how they feel. Don’t put on your detective hat and try to figure out if x means y and that leads to z. Because if a person cares for you, they will make it known. And you deserve a person that makes it known how much you mean to them
When Anyone says it’s not possible to keep big cities clean I’m just show them this. Japan is one of the most densely populated countries don’t gimme that bs
