How time flies! It has been a long time since we last met. But soon we will meet again, because this summer I’m planning to visit London to learn about the local culture. I’ll arrive in London on July 20th and stay there for a whole week. I’ve never been to London before, so I’ll be appreciated if you could recommend some places of interest which are worth a visit. During my stay there, I’d like to pay a visit to you. Would you please tell me when you are available? I’m looking forward to your reply soon.
