I've left my lunch at home.
Shall I open the window?
What time shall we meet?
Shall we go to the cinema tonight?
Where shall we hace lunch?
Yes, please. It's too warm!
You could buy a sandwich from the canteen.
What about ten o'clock?
There's a new restaurant by the university. Shall we try it?
I'm sorry but I'm having dinner with my grandparents.
