Dear Laura,

I just heard you tell an old story of gift giving and unselfish love in your program. You doubted that such unselfish love would happen in today’s world. Well, I’m here to give you .

I wanted to do something very for my fifteen-year-old son, who has always been the perfect child. He all summer to earn enough money to buy a used motorcycle. Then, he spent hours and hours on it it looked almost new. I was so of him that I bought him the shiniest helmet and a riding outfit(全套装备).

I could wait for him to open up his gift. In fact, I barely slept the night before. Upon awakening, I went to the kitchen to the coffee, tea, and morning goodies. In the living room was a beautiful keyboard with a : “ To my wonderful mother, all my love, your son.”

I was so . It had been a long-standing joke in our family that I wanted a piano so that I could lessons. “ Learn to play the piano, and I’ll get you one ” was my husband’s .

I stood there shocked, crying a river, asking myself how my son could this expensive gift.

Of course, the awoke, and my son was excited with my reaction. Many kisses were , and I immediately wanted him to my gift.

As he saw the helmet and outfit, the look on his face was not what I was expecting. Then I that he has sold the motorcycle to get me the keyboard.

Of course I was the proudest mother ever on that day, and my never hit the ground for a month.

So I wanted you to know, that kind of love still and lives even in the ever-changing world of me, me, me!

I thought you’d love to this story.

Yours,

Hilary

To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (山魈, 西非洲产的大狒狒) covers her face with her hand she is actually sending a serious message to her fellows: “Leave me alone!”

Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require solitude.

Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures — the ability to communicate with the hands in a meaningful way. “By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a ‘do not disturb’ sign,” said Mr. Laidre.

While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills.

Curator （园长） Sarah Forsyth said: “We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We’re not sure why she started doing it but it could be as simple as ‘I can’t see them, so they can’t see me’. It really does show you how intelligent mandrills are.”
