I hate when that happens
As I completed my work there I arose and shrieked like a scared little girl, and I'm sure I nearly fainted. I thought somebody had better call 911.
Then my memory returned and I regained my senses.
We had had beets for supper the night before.
I should devise some simple plan for reminding myself of this fact the morning after. It's not the first time this has happened, that's for sure.
