"Tradition says Martin Luther started using the trees to represent something - the old Martin Luther who started the Protestant Reformation, not Martin Luther King Jr. of the Civil Rights movement - but that doesn't really hold up considering it was a Germanic tradition long before he came along, so another theory says he just added the lights, but no one is really certain what exactly it represents or who started it.

Plus, fake trees don't decompose very easily. In fact, depending on the tree, it takes less time for a new tree to grow than it does for a fake tree to break down in a landfill."

It was melted down and new ores added at least twice, meaning it is a different item than what was originally cast. And don't you find it interesting?" He paused and turned to look back at her with a frown.
