Dear Mark,

Recently I attended a local open-air festival of street music. It took place in my town last weekend. I visited the festival with my friend.

Even though it was rather cold and snowy, we felt warm and comfortable. The music was very nice and we danced most of the time. There we could buy various kinds of fast food, drinks and so on.

I liked the festival, and I wish they made it in summer. It would be super exciting to visit it once again.

Do you like such festivals?

I am looking forward to your letter,
