Some men give as little light in the world as a farthing tallow candle, and when they expire, leave as bad an odor behind them.
Frequently, an author gets "orphaned" at a publisher. What this means is that an editor buys their book, then ends up getting fired, promoted, or transferred to a different job somewhere else. It sucks for the author because suddenly the person who liked your book enough to buy it isn't around to help you edit and promote it.
