When Disappointment Strikes
When we are disappointed by the actions, or inactions, of someone else we have a few possible responses: Confront the issue or Ignore the issue
That's pretty much it as I see it.
The choice is up to us. I suggest confronting the issue head on. Don't let it morph into something bigger than it is. And show a lot of grace when you do address the issue, chances are you'd like to be shown grace when you are the one doing the disappointing.
