Dear Peter,
I'm sorry I haven't written sooner, but I've been busy recently.
Thank you for your invitation. I am so happy that i've received it!
The date of the party suits me. I've already booked a ticket on a night train. It leaves from Warsaw at 9pm so I'll probably arrive in Praha about 8am. I'ii be much earlier than the party starts, so I can help you with preparations, if you want.
I'm so glad that I'll se you at last! After all, we've corresponded for 3 years and we've never seen each other.
Do you remember Emily? I've written about her a couple of times. She's my best friend and I wanted her to go with me. Don't you mind it? She's a great person, really worth knowing. No one tells jokes as good as her and you just can't be bored with her.
Anyway, I must go now, as it's getting late and I have a lot of work.Can't wait to hear from you soon.
Best wishes,
Kate
