DD7 is in a mood this afternoon. I won’t let her buy a specific souvenir, part of which was a display case and not for sale. 
Anyway, she was grumpy for a while and then I accidentally ran over her toe with the stroller. 
She is doing better now and no longer grumpy, but it just goes to show that even a rest day can turn sour. Moods are unpredictable.
