Read the email about a holiday.
Hi Andy
How are things?
I'm having a great holiday. I'm staying with my mum's
friends in Germany. They live in Marburg, a beautiful
town (1)
Mum's friends have got two daughters, Susi and Katinka.
They're 14 years old (2). They're a lot of fun - but
.
they're identical twins so I don't always know who is
who! They speak excellent English, but I also practise my
German every day, of course!
The town is really interesting. (3)
and there's a
castle at the top. There's also a river called the Lahn.
The university is hundreds of years old, and there are lots
of students everywhere.
It's carnival time - that's called 'Fasching' here. (4)
and there are parades where people wear funny
costumes.
At the moment we're sitting in an old café drinking hot
chocolate with cream
(5). Delicious!
See
you soon.
