I ( walk ) walked briskly up the path to the cottage which I ( not visit ) haven't visited for 2 months . The grass ( grow ) grew to a height of about 20 centimeters. Hardly surprising , since it ( rain ) rained a lot , although that particular day ( be ) was dry and sunny . It was late afternoon and it ( get ) was getting colder . I (put) put my hand in my pocket , (get) got ut the key and ( unlock ) unlocked the door . Before leaving , I ( lock ) locked every door and window . As I ( step ) was steping inside , I ( notice ) noticed that the air (be) was fresh . That ( cannot ) couldn't be right . ( I imagine ) imaginedthings , or ( I hear )I heard a creak from the top of the stairs ?
