I have an orangutan story, too. We were at the DC National Zoo. A young male was busying himself with some fresh straw. After patting it down properly, he fetched a near-by blanket and, after a few attempts, managed to throw-spread it to nicely cover the straw matress. As he prepared to lie down on the newly-made bed, he noticed a stray straw on it and delicately removed it.

By this time, his performance had gather a large admiring audience. He stretch out on his bed, and immediately began to ... I'll be discrete here ... Suffice it to say the parents in the audience, immediately shielded their children's eyes and "headed for the door"!

PS: The use of "they" for an individual, is getting out of hand. We urgently need a gender-neutral singular pronoun. John, for the sake of consistency at least, search for the word "it" and replace it with "she". ThanQ!
