There's an old Mongolian story.
A man had a daughter who suddenly became very ill, she had become melancholy and tired, worried he went to the local shamen, "have you got a dog?" the shamen asked.
"Yes" he replied.
"Then you must get rid of the dog."
"But he's a good dog" he protested.
"If you don't get rid of the dog then you're daughter will not get well." the shamen insisted.
The man went away, he didn't want to kill the dog but couldn't think what else to do, the next day he found a cave that was enclosed so the dog couldn't escape so he placed the dog there and everyday he went to attend to it.
Within days his daughter returned to health.
I'll tell you why after "The Big Bang Theory." in roughly half an hour.
