Переведите, убедительная просьба перевести со смыслом
I'm so happy to be here in Bergen for our holidays. I'm having a fantastic
time and I just love this part of Norway. Lee and I are staying at the historic
Royal Hotel. At the moment we are having a cup of hot chocolate and enjoying
the spectacular view of the harbour.

The weather is cold, and perfect for skiing. The seven mountains around the
city are covered in thick snow. The famous fjords are stunning. In these quiet
waters you can sail past mountains, waterfalls and fields. We spend most of our
days hiking in the mountains with our Norwegian friends, Erik and Katerina.

Norwegians really love the outdoors. They're very friendly and kind to us. I
think they're really good-looking. Most of them tend to be tall, with fair hair
and light blue eyes.

The food is delicious. Norwegians like eating fish and seafood, especially
salmon, shrimps, lobster and caviar. I just love eating fresh bread and smoked
salmon for lunch.

Next week we're going to Oslo. I can't wait to visit the Outdoor Folk
Museum. Lee is not so keen, but I’m looking forward to it. Our flight is leaving
from Oslo next Friday, so I hope you'll receive this before we get home!

I think you should come here next year. I'm sure you would love it!

See you soon.

Love,
Susan

Муха сено к возу носит,
