Once upon a time a man bought a bamboo plant at his local nursery to plant in his back yard. Having heard some rumour that bamboo could be a little impolite, he wanted to assure himself that his bamboo was going to be well-behaved, and grow socially responsibly. So he asked the bamboo:
“If I plant you here, you’re not going to be ill-behaved and take over the entire backyard, are you?”
