This is the quote that finally pushed me over the edge.

How do you accept an apology you never got? If you never got it there is nothing to accept. If you can get beyond that fundamental flaw in this quote then how does it make life easier?

How about just being a stronger person and realize that the world is filled with a lot of bad apples. There are just bad people who do bad things and that's not going to change any time soon. That's what needs "accepting" here because once you accept that you can move on and avoid those bad people.
