One by one, the lights in each skyscraper, office, apartment block and tourist attraction began to switch off.
‘What’s wrong?’ Sarah turned to Dan. ‘What’s going on?’
Dan reached into his jacket and pulled out a small candle and a box of matches. Lighting the candle, he turned to Sarah and grinned.
‘Earth Hour – I nearly forgot, with all the excitement.’
Sarah laughed and punched him gently on the arm. Dan put his arm round her shoulder and pulled her to him, kissing her gently.
‘It’s been a blast, thanks,’ he said.
Sarah smiled and nodded, not trusting herself to speak as they sat in the enveloping darkness.
