To Thea from Kate

Hi, Thea!
It's Kate, a student from Russia. I'm so sorry I didn't reply your letter long ago! When all our students received the letters from your class I was at the sanatorium. Then I was preparing for my exams. Now the exams are over and we are looking forward to having our long summer vacation.
Thea, I promise to write to you very often in the next school year! I wish you to have a lot of fun during the summer!
Best wishes,
Kate
