It was two years ago in winter when I went with my family to Engadine in Switzerland. The journey by car was pleasant until we reached the bottom of the Julier Pass(尤里尔隘口) when it began to snow.

Suddenly, the weather became very bad and soon we found ourselves in a storm. On the top of the pass, the visibility(能见度) was almost zero and we had to guess where the crash barrier(防撞护栏) was. It was terrible, the snow turned into ice and stuck to the windows despite the heating being set at full blast. Several times I had to get out of the car to clear the ice from the windshield(挡风玻璃).

But the way down towards Silvaplana was less stressful and we knew that we would arrive in paradise(乐园). It snowed without interruption the first day of our holidays and not being used to this natural weather, we found it simply magical to watch so much snow falling down on the mountains.

The following day, in this large, amazing area made up of frozen lakes and rivers between white mountains, we discovered a little hut next to the cross-country ski tracks, close to a farm. There was a fridge in this heated wooden cabin that contained milk, cheese and yoghurts for self-service. There was a list of prices for each item. You took what you wanted, then wrote down the total on a notebook what you had taken and put the money into an open box and if necessary took the change.

Where else could you find such trust? As I’ve already told you, Engadine is a paradise.
