Do you believe in fairies?
A relative of mine used to enjoy a drink. She often lost all memory of the later half of the evening.
Waking, after entertaining the previous night, she would dread the thought of having to clear the consequent mess. Very often she would stumble about the house to find all dishes washed and put away, furniture straightend and the Hoover recently deployed.
She attributed this phenomenon to the 'Booze fairies'.
