I took my anger out on the wrong person, I am sorry

In my ill informed mind I was right to be angry.  NOBODY told me what the plan was, and when it wasted all our time I was good and pi$$et off.  If "somebody" had taken the time during the day to explain things to me, I would never have been as angry as I was.  Given the track record of "someone's" past B S you can surely see why I was how I was.  I am sorry you took the brunt of it when I thought you were being taken advantage of. 
Interestingly it's been 4 days since" someone"  has spoken to me.  Meh life goes on.   Now that I know the facts (too late) I sincerely feel bad I let my anger flow onto you.  I am very sorry.
