He missed his Father's training lessons, and if that wasn't something that shocked him. He and Hermione complained most of their childhood about how he would force them to go for runs around the mansions quidditch pitch every weekend in order to stay in shape, he claimed it was why he didn't tire easily on the battle field. He missed how his Father would stay with them, showing them over and over again the curses and hexes he was teaching them until they mastered it. Although it was due to their Mother's interference they hadn't learnt the unforgivables yet, they had finally agreed after a long screaming match to wait until the twins were 13. Harry smiled softly remembering how foul his Father had been after that night, the lower Death Eaters suffered greatly for his Wife's stubbornness. But he loved her all the same which amused the twins too no end, they knew Dumbledore believed their Father didn't know how to love. How wrong he was. Nothing meant more to their Father than them and their Mother, and despite growing up to be the perfect weapons and trained to fight and survive their Father always made sure they knew it.
