5. that the General Manager, Mr. Brown, must be away for a marketing conference in Paris around that time.

Hi, David,

It’s great to hear that you’re coming soon.

You can travel by plane or train. If I were you, I’d do it by plane. Why not contact a few travel agents? They sometimes offer cheap flights.

It would be worth bringing another form of identification, like an ID card, because you won’t want to carry your passport around all the time. You ought to bring a little English currency with you, in case the banks are shut when you arrive. However, it’s a good idea to have mainly travellers checks, as they’re much safer. By the way, you’ll probably find it’s well worth getting a student card — you’ll be able to get all sorts of discounts, particularly when it comes to traveling around.

There’s just one other thing — you’d better remember to get in touch with us when you’re over here, or we’ll be very upset!

Love,

Chen Bin
