"Can't you sleep?"Suddenly there came a voice behind John：It was his mum．Then she saw two painkillers in his hand．
"I see that the toothache has come back．"she said．
"Yes，it has．Maybe that appointment was not a bad idea．"said John．He took the painkillers with some water．
"But I have can celled it．You have to make a new appointment next morning，"said Mum．
