I'm into stew
And grow dump,
Because of you
Float in my mind.
Your lips – are honey,
Your eyes – sky’s blue.
Remember, darling,
I’ll always love you.-

Main Room
Gus: Hi, guys! I'm in an internet cafe. It's raining heavily outside. I'm fed up with this weather. It's raining all the time.
Nemo: I don't know how you can live in Scotland. There are nicer places to go to study.
Gus: Scotland's great. It's the winter I don't like. It's grey almost every day. I hate winter.
Amelia: Hey! You think that's bad! It's freezing here in Switzerland. It's snowing again. There is so much snow sometimes that I can't even go out.
Gus: That's not my kind of place, then.
Nemo: It's summer here in Australia and I'm having a great time. I'm sitting on the balcony at the moment and it is very, very hot. I love the summer.
Amelia: You are lucky.
Nemo: I am. Anyway, how are things going for you? прочитать по англиски-
