Dear Linda
Hi! How is it going? Thanks a lot for your postcard. Sounds like you had a great time in Switzerland.
Well we went back to school today for the first day of the winter term. Boring! I cannot believe how quickly the summer holidays went. Actually it was not that bad. Ther are a couple of new guys in my class this year and they both seem realy nice. One of them is really good at football. I am going to try to get him on the team.!
Anyway I would better go now. I have got loads of homework to do to night. 
Write soon!
All the best!
