Ответ:

делаю по тому плану, которфй нам показывали в школе.

Dear Sally(имя друга),

Thank you for the letter. It was great to hear from you after such a long time. I really should have written sooner. I have been busy with my exams.

the last place I was on vacation was Bali. it's very nice and hot. Yes, I had problems on vacation, for example, we mistakenly disabled internet on the 3rd day of our vacation, but everything was fine.

Hope to hear from you soon.

Best wishes,
