Doing

I am disappointed in humanity
Too many people say that they will do something and don't
The missed coffees, the follow up on a great talk, the truth in friendship or relationship that gets held back,
Overall the expression of doing something but not living up to it.

I think one thing that could make this a bit easier to accept would be owning it after the fact
The coffee is missed and you try to reschedule, own that it won't happen so it can be let go

Maybe I just expect too much and should lower my standards.
