Dear Alan,
Thank you for your last letter. I was so glad to received your letter. You told me that you are not stay-at-home and that you like to travel. You ask me about travelling and and with whom I travel.
As for me I like travelling. I was in different countries, met many new people.
Most often I travel with my parents. But sometimes I travel with friends.
Most of all I love to travel by plane. Although it is an expensive mode of transport, but it is the safest.
Best wishes,
(Имя)
Смотри, как-то так. Дополни чем-нибудь еще. А то тут мало этого. Когда сдавала английский, минут 30 тратила на написание письма. Думай, что еще можно добавить.
