I believe that I am taking a note from my cousin Audrey's weblog and I am going to post an open note to the people of the world.
Dear People of the World:
Just a reminder- yelling at people who can't do anyhting about the thing which upsets you is stupid. It makes them feel belittled and angry and it makes you look insensitive, self-involved and out-of control.
In the future, please try to limit your loss of temper to the people who are A. to blame or B. can do something about the thing which has upset you.
