If you're tired, sleep. If you're hungry, eat something. Take care of yourself. Self Care Haiku, found on the internet. -- Anon Guest
It was a decorative plaque, almost in the style of the Ten Commandments in the way they were arranged.
If you are tired, sleep, it read. And onwards into other rules.
If you are hungry, eat something. If you are thirsty, drink. If you are ill, take medicine. If you are dirty, bathe. If it is broken, get it fixed. If it is ruined, replace it. If it is gone, mourn its loss. If you are sad, cry. If you are angry, yell. If you are lonely, come to me. I am here for you.
It was in an art gallery, and the title of the piece was, Owner's Manual For the Human Body.
