Dear Barbara,

Thank you for your letter. I really miss you, too, I think it's a great idea to visit you in London. All of us hope to get the invitation fetter very soon.
What can I tell you about my holidays? This summer I was in the country. I was very lucky. The weather was fine ail the time. My friends and I spent a lot of time outdoors swimming, diving, riding our bikes and skate-boarding, we also enjoyed picking berries and gathering mushrooms in the nearest forest, in the evening we usually made a fire, played the guitar and sang songs. I took a lot of pictures of my friends and of myself. This one is for you. I hope you'll recognize me. You see that i am bigger than I was last year.
I know you have a sweet tooth, Barbara, so I asked my granny to make some cherry jam, (I helped her a little). if we come to London, you'll have to try it.
With lots of love and best wishes from me and my friends.
