All plants communicate through their root system. Even cross species. Don't think that when you cut down a tree, or pull out a weed, his neighbors are not crying in grief, for the loss of their friend. Especially trees that have been growing together for decades.

Sounds a lot like the American political system.
"What they found is that like any true vampire, the dodder has a "silver tongue," sweet-talking its victim into lowering its defenses."
