Dear Karen,
I going to London next week, because Joey's party on Thursday and I do not want to miss it. I hope Sarah there. She in London for a fortnight by then, so she able to get to Joey's house with no problem.
Thank heaven Joey is have this party, because at last I have a chance to talk to her. If everything goes well, this time on Thursday I at Joey's, enjoying the party, and rchatting with Sarah. I hope we get on well together.
Of course I am nervous, but by Friday next week, all this over. Sarah met me, and who knows what happen next.
