Dear Anna,
Hi, how are you? I hope you are fine. I'm writing to you because I must talk about the interview.
I'm sorry but I can't come for you to the bus station, because I have to be in my job. You should drive to my house by taxi. You know my adress, I think you could drive about 15 minutes.
In our summer holiday I could show you the best places in my city. I think it would be nice when you meet my friends. We can travel by plane and sunbathing near the sea.
You should take a casual and comfortable clothes. In this time in Poland is beautiful weather. Remember about your swim-suit.
So, I'm waiting for you.
Yours, XYZ. :)
