"My father had recently died, leaving his house to me, so we went there. It was close by and had more rooms. The cabinets were still stocked with Muggle liquor and we drank it. We didn’t talk much, until we weren’t. Both were drunk and she made a mistake in the contraceptive charm. I didn’t notice it and normally I would have cast it, but I couldn’t find my wand and when she offered me hers, the wand did not work for me. I guess I used too much Dark magic and the wand did not want me to cast a spell, so she did it."
