Harry had not received a letter from Sirius in over two weeks.
Two weeks was not really very long, but it still left him feeling somewhat out of sorts. After all, during the first two weeks of term, as well as the summer holidays before that, he had received two letters from Sirius every week.
In most of his letters, Sirius simply shared something new or gave Harry a little tip about magic. Harry loved the feeling. What Sirius gave him was something he had never experienced growing up, something he had thought he did not care about.
A father's love.
But suddenly going two weeks without a letter was a little hard for Harry to get used to, even though Sirius had told him beforehand that he would be going abroad for a while and would find it less convenient to write.
That had prepared Harry somewhat, but when it actually happened, he still felt a little uncomfortable.
Still, he only felt that way when he had some time to spare. Most of the time, Harry was too busy to worry about such things. There were quite a few headaches to deal with this term.
The previous school year, Harry and Ron had both failed their final assessments in Astronomy and History of Magic.
That was perfectly reasonable. After all, they had gone almost an entire term without doing their homework, relying entirely on the Enchanted Quill. It would have been strange if they had still managed to pass.

Neither of them wanted the same thing to happen again, so
