1.13. A man lies dead next to a cactus. Stuck to the
cactus is a slip of paper. (TO)
1.13 answer: The man was lost in the desert for days. He couldn’t find
any landmarks, so he started sticking slips of paper to cactuses he passed.
After another day of walking, with almost no water left, he came across this
cactus, which had a slip of paper on it already; he knew that he was walking
in circles, so rather than wait to die of thirst he shot himself. (See also
