I live in San Francisco, where it seldom snows. But if you get in a car and drive a few hours, you’ll arrive at these beautiful snow-covered mountains. Last week, my friend Ollie and his grandmother Mary invited me to go skiing with them. It was colder than I’d expected. Mary offered to lend me her scarf. It was the softest, warmest, most awesome scarf, and Mary had knit (编织) it herself.
“These old knees need a rest!” Mary said after a couple of hours of skiing. “You two go ahead and take another run. I’ll be in the lodge, reading by the fire,”
So Ollie and 1 took one more ride on the ski lift up the mountain. As we looked around at the trees and watched people zipping down the slopes, I said, “This one piece of yarn (毛线) on Mary’s scarf keeps tickling my chin.”
I pulled on the end of the yarn, thinking it was just a loose piece that had separated from the scarf. But the more I pulled, the longer the piece became.
“You’d better stop.” Ollie said, “The scarf is unravelling (散开)!”
When I took off the scarf to see what she meant, I was horrified. “Oh, no! I just turned Mary’s special scarf into half a special scarf and half a big pile of yarn!”
It was one-of-a-kind-thing that I'll never be able to replace! “What am I going to do?” I asked my best friend.
Ollie suggested, “You could say you accidentally dropped it.”
“I hope you’re kidding.” I shook my head.
“You know 1 am joking around,” said Ollie, “Honesty is more important to Mary than anything. You just have to tell her the truth.”
Right then, it was our turn to get off the lift. 1 shoved the wrecked scarf into my jacket pocket and skied extra slowly down the hill to the lodge.
I wasn’t in a giant hurry to tell Mary the news.

We burst out laughing when we saw how terrible my first tries at knitting turned out.
