Once upon a time there was a couple, living in India. They were very happy together, and then the newly widowed mother of the wife came to live with them. She talked a lot, and their peaceful quiet existence was changed. The husband went to see his Guru.
"What can I do? My mother in law talks all the time and never gives us a moment's peace!"
"Get a cat," was the Guru's response. And so, he did.
The Guru responded, "Get a dog." And so, he did.
