True story. We used to live in Southeast Texas, where the invasive
Chinese Tallow is widely considered to be a noxious weed. When walking
around in our yards, we habitually pulled up sprouting tallow trees,
much as one would pull up any weed. As a courtesy, we would do the
same in our neighbor's yards or when visiting friends.

One of my circle (call him Bob) was visiting in Arizona and stayed at
an RV park. As the evening softened, Bob took a stroll around the
campground and habitually pulled up a few tallow trees. The owner saw
him and threw a fit! he had planted the worthless things and paid good
money for them at a nursery.

Bob promised to send him a dozen or so decent sized tallow trees by
express mail as soon as he returned home, and did.
