How did Mark get there?

M: Hello.
W: Oh, hello, you must be a new student. Did you find us ok?
M: Well, I got a bit lost and I had to ask a stranger, but I got here eventually.
W: Oh, dear. Have you come far today?
M: Only from Britain. I was staying with my brother.
W: Oh, good. How did you get here?
M: My brother took me to the railway station and I got a bus at this end.
W: Aha, well, you’d better tell me your name, so I can find your form.
M: It’s Mark Bern.
W: Bern, Bern. Ah, yes. Oh, you’ve changed since this photo. What happened to your beard and moustache, and you are not wearing glasses, either?
M: No, I thought I’d better look smarter.
W: Here is the key to your room. It is 501.
M: Thanks. How do I get there?
W: Go to the end of this corridor, turn left and it’s the third door on the right.
M: Thank you. Oh, there is a meeting for new students. What time is that?
W: Half past five in the Common Room on the ground floor at the other end of the corridor.
M: Thanks a lot. Bye.
