Dear Helen and Martin,
We are having a great time in Scotland. We are sitting in a café near the sea. Steve is reading a magazine and I’m writing this e-mail to you. But Linda is really bored here, she is sitting in her room and watching TV.
We usually go to Spain every summer but this year we wanted to see Scotland. We go for walks every day in the mountains. We don’t go swimming. It’s too cool! Linda is really missing London.
See you soon.
