The first term went by in a busy round of classes and games. Albus found that he liked being a Slytherin. Everyone in his house had a quiet dignity and a certain self sufficiency that appealed greatly to him. He visited his brother and his cousins in Gryffindor every once in a while and as he often told Scorpius, he found most Gryffindors to be a little too loud and boisterous for his taste.
Albus and Scorpius spent virtually all of their time together and by the time the Christmas holiday rolled around, they were pretty much inseparable. Neither of them was looking forward to the holiday at all. Twenty days without seeing each other seemed a little too awful to contemplate. They would just have to find a way to convince their parents to let them meet at least a couple of times a week.
Harry and Draco had had more than three months to get used to the idea that their sons were best freinds, but nothing could've prepared them for the way their sons moped about the house, looking miserable, just two days after the holiday had started. What made it worse was that it wasn't anything very obvious. There were just a few subtle differences in the boys' behaviour, but both Harry and Draco knew their sons well enough to see that the boys were out of sorts.
And before they knew it, they were writing to each other, making plans for their sons to meet, dropping them off and picking them up. By the time the holiday was over, Harry and Draco had ended up meeting almost every day. It was impossible not to get to know each other a little bit and by the time the holidays were over their sons went back to school happy in the knowledge that they had manipulated their fathers so well, that the two men had actually started to become friends.
