Daniel 5

There is a new king, Belshazzar, son of Nebuchadnezzar. He is having a party, praising the gods of gold, silver, iron, wood, stone etc. In the midst of this party a "hand" comes and writes on the wall... Ok, seriously strange... No one knows what it says, none of the magicians can figure it out so the king eventually calls David in again. David tells the king the story of his fathers rise, fall, and new life in the Most High God. He says, "But you, Belshazzar, his son, have not humbled yourself, though you knew all this... You did not honor the God who holds in his hands your life and all your ways..." Nevertheless, David interprets the writing on the wall and honestly, I'm a little confused about where the story goes from there...
The writing says "Mene (mina, money) : God has numbered the days of your reign and brought it to an end. Tekel (shekel) : You have been weighed on the scales and found wanting. Peres (divided or half mina) : Your kingdom is divided and given to the Medes and Persians."

What does it mean he was weighed and found wanting?
Why didn't God give him another chance, like he had with his father? I think because he knew all that had happened with his father and never "humbled himself..." But still pretty harsh because after he promoted Daniel the king was slain and a new ruler took over. Sucks for him.

And what can I learn? How can I apply this in my life?
Well, I think I better learn from the mistakes of my parents... What does that mean?
A little confused on this one...
