['I am a planner.  I had planned a big getaway today.  Only after I arrived did I realize I had made a huge mistake!']
Where did you go and what happened?
So, for the last two months, I had been emailing a Shaker museum about visiting their location.  I had worked out all the activities for the day.  I found out just today, I had been emailing the wrong location.  So when my family and I arrived at the real location, I realized the mistake I had made.  We were so nervous and upset, we really didn't know what to expect.  Thankfully, it turned out wonderfully!
