Вот пример ответного письма для вашего друга Джастина:
Dear Justin,
Thank you for your email! It sounds like you had an amazing time at the camp! I have never been to a summer camp, but I think they are great for teenagers.
I believe that spending time at a camp helps teens develop important qualities like teamwork, leadership skills, and independence. They also learn to make new friends and face challenges together, which can be really fun!
I hope you share more stories about your adventures. I look forward to hearing from you soon!
Best wishes,
[Ваше имя]
