Oh, a pity! It’s raining again? Is everybody here? Good. Now listen carefully. I wish the weather is better here for you. It’s very usual to have so and so much snow and rain here at this time of year.

Some of you are asking about tomorrow’s activity on the way here. Well, we’re going to climb the mountain unless the weather gets much better during the night. OK? So, provided that it doesn’t snow too heavy tonight, I’ll see you back here at six o’clock. Set your alarms for 5:30. We’ll take our breakfast with them because we won’t reach the top of the mountain unless we set out early, before it’s light. So be there tomorrow morning with everything you need. You’ve all got a list—you need a whistle in case you get separated from the rest of the group, warm waterproof clothing and gloves, and a good pair of boots. Don’t forget to bring maps I gave you yesterday. I’d rather you didn’t bring large cameras and video cameras.

It’s time we had dinner now, so if that anyone has any questions, you can ask me on the way to the dining hall. Let’s go.
