I heard a story once about a person who contacted a university botanist
about his trouble growing cacti on his windowsill in the Midwest.
The botanist tried to explain that water requirements for cacti were different
than those for, say, an African Violet. She pointed out to the person that
cacti grow naturally very well in arid environments like the US Southwest,
where they get infrequent rain. The person said he thought he understood, and
would give it a try. A year or so later, he wrote to the botanist to report
that his cacti were now quite happy on his windowsill. He watched the national
news each night, and when the weatherperson reported rain in Arizona he
watered his cacti!
(BTW, this is not my original story; I heard it from someone else)
