I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said.
'What a pity!' Susan exclaimed.
Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said.

'Certainly, 'the girl said, 'but they are for next Wednesday's performance. Do you still want them?
