When Ignorance Is Bliss

I can't complain with all this grub I'm getting from dawn's first crack until the sun's last setting. I'm glad to be the happy son of fate, except for the fact I'm putting on some weight. The people here all seem so happy too but for one who's feeling very blue. by which I mean the chieftain's elder son, I have a hunch on why he's feeling glum. His younger bro' turned up the other day, forlorn and broke, the gossip-mongers say. His fortune's gone and his last farthing's spent. He really chose a fine time to repent. All's past, forgiven and soon to be forgotten! The reason's clear his brother feels so rotten. To celebrate they're putting on a ball with tons of guests and food and drinks for all. I sometimes wonder where things are leading to. But I'm well fed, so I should give a moo?
