Rodolphus just grinned before shaking his head, his son's question had brought back a lot of good memories. "Your mother and I knew each other for years before going to Hogwarts, you know, with all those bloody parties and the lot. When we finally got to Hogwarts I developed an interest in her, so in our second year I wanted to talk to her. When she went over to talk to Lucius I crucio'd her. The rest as they say is history."
