Be careful what you say before you have all of the facts

I am frustrated this morning. As the minutes and hours tick, tick, tick by, I know what happens. Frustration leads to aggravation, always the hardest emotion for me to control, and I say something intemperate. But I don't know all of the facts yet. Even when I do, even if they precipitate aggravation rather than head it off, I hope that I have the forbearance not to say something that I later regret.
