Hi Tom,
Thanks a lot for your letter! It was so nice to hear from you. How are your parents doing?
First of all, I can't wait for my trip to start! I bet we are going to have a lot of fun in Scotland together! I think we should make a list of things we are going to do there. What are your suggestions? I would really like to visit some of the most famous castles of Scotland. What's more, (Taylor Swift) is having a concert in Edinburg, so let me know if you would like to go! Also, please let me know what the weather is like there and tell me what clothes should I bring. Is the anything else I should take with me?
Please say hi to your parents! Can't wait to spend my holidays with you!
Love,
Marina
