It was still dark when he rose from his cupboard. Master had offered to make him a bedroom but Kreacher had declined as house elves were not supposed to have bedrooms. Instead he had agreed to Master cleaning and replacing some of Kreacher's dirty rags with clean, soft, blankets. It had been many years since Kreacher had been given to his Master, he remembered how much he had dreaded it in the beginning, feared it would be like having Master Sirius back.
Kreacher had been wrong.
Master was kind and fair to Kreacher. He never yelled, punished, or did anything unkind to Kreacher at all. In fact, Master had offered to free Kreacher after the battle at Hogwarts, but Kreacher refused. He had come to like his Master and would serve him until he died.
As Kreacher got up and stretched before going about his business he reflected on how the past years have been with Master and his family. Kreacher remembered when Master had come back from the school to Grimmauld Place. He had been tired and sad. Master never asked Kreacher to do anything but Kreacher always made sure Master ate. He often found Master sitting alone in the library just staring off in to nothing. In the beginning Kreacher hadn't known what to do, he didn't really know what his Master wanted from him so he hid in his cupboard and only came out to cook and make sure Master went to bed.
As the weeks passed and Kreacher saw that his Master wasn't improving he started to clean up the house. He started with Master's bedroom and then the toilet. He had managed to get every room in the house in to almost perfect condition, every room except the library where Master sat alone in silence. Kreacher was afraid to go in there and disrupt Master Harry. He didn't want him to get angry and throw Kreacher out.
Another week passed before Kreacher had worked up the courage to go in there. At first it was just a little dusting. Then it was picking up papers and putting books away. When Master said nothing Kreacher went about his business until that room too was as spotless as it could be. When there was nothing left to do he made tea and brought it into the library and placed it on the table next to Master Harry. He then decided to sit in the corner and keep Master company.
This had been their routine for several days before Kreacher realized that when he brought Master his letters they were not being opened. Kreacher had begun to worry, but had not known what to do. He had decided that Master needed help and if that meant Kreacher was going to be punished so be it. Kreacher went to get Masters friends.
They came over and seeing them seemed to bring Master back to life. They stayed for several days until they were sure Master would be alright on his own for a few days. Kreacher remembered that when Mistress Hermione had left she had made Kreacher promise that if tomorrow Master went back to his old ways Kreacher was to come get her immediately. Kreacher had promised and with that she and the red headed boy had left.
Kreacher had been worried that Master would be angry with Kreacher that he had betrayed his trust and gone to his friends, however Master thanked him and praised his job on cleaning the house. Since then Master rarely had moments when he seemed lost to the world and say alone in silence. Kreacher knew that when that happened he was to go and get Hermione and Ron if it lasted long than a few minutes.
However, since Master had married Kreacher's Mistress these moments had gone completely. Kreacher liked his Mistress as she was just as kind as Master. As Kreacher thought of his Mistress he realized that he would need to stop his reminiscing and get started on breakfast. The family would be up soon and today the family had an outing to Diagonally, which Kreacher must prepare for.
With a final stretch Kreacher set about his task getting his family ready for their day.
