Dear Kairos,
How are you? How have your family been? Many thanks for your last letter. It is great to hear from you again. I’m sorry I haven’t written for such a long time, but I’ve really busy studying English to pass the B1. I hope you and your family are well.
Anyway, I must go and get on with my study. Give my love to your family. We must try and meet up soon. I look forward to hearing form you soon.
Best regards,
Wolf
