Sia this story was posted by Anjani in the WU yesterday. They showed almost the same where Parvati misinterpreted Shiv's signals. Please read the post of Anjani that I post again.
Shani has boon from Parvathi according to scriptures, that no work would begin with out his drishti. Shani despite his bad reputation, is not that bad. He does a lot of good as well. It is karma that is reflected in our lives. Just like Yama, Shani is also known as sama drishti. Shiva himself gave him the title "eeswara". No other graha has been bestowed with this honor.
This is what I found on the web fro Puttaparthi Swami Vedic Astrology website :)
There is a tale of Parvathi wanting a new abode in Kailash, and when Siva (finally) granted the wish for an abode, Lord Brahma demurred and told, "Not wise, not wise!" for he could sense the gaze (drishti) of Shani would bring matters to grief. Siva went to ask Shani to avert his gaze from the new house. To cut a long story short, there was misunderstanding of the signals, Siva beat his dhamaru (because he was doing the tandava dance for Shani), Parvathi misunderstood the message and burned the house down. The moral of the story is that none may escape the drishti of Shani.
