Dear Kirsten,
Hi! How are you? I’m writing to say thank you for letting me stay with you.
Your family’s flat is very different from our cottage. The rooms in your flat are smaller than the rooms in our cottage. We can go for a walk in the countryside, but we can’t go to the cinema or theatre. We can enjoy peace and quiet, but we can’t see a lot of people. I guess no one can have everything they want at once.
Visit me soon.
All my love,
Amy.
