Dear John,
Thank you for your letter. I'm sorry for not writing to you sooner, I have been busy at school.
In your letter you asked me about summer in my country. Well, I should say it's really hot here, especially in July and August when the temperatures may reach 45 °C. If you decide to come here in summer, make sure to have a broad brimmed hat.
I like summer anyway, because I don't have to go to school. And what is your favourite season? What is summer like in the UK? How do you spend your summer?
Write back soon.
Best wishes,
