This conversation had also caught the ears of the other adults, those who have personally known James and Lily. Sirius answered, telling a story of how he and Remus had known James and Lily since they were children. And Sirius was truthful about how James, himself, Remus, and another man who ended up being a Death Eater as an adult, were pranksters... and sometimes bullies towards the greasy-haired guy in the room, Severus, and how Lily at first hated James because of the boy's sometimes antagonistic attitude. But as they got older, James started to change, finding himself attracted to Lily and tried to change his ways, to court her. And eventually, Lily had given James that one chance to impress her. That's how they had fallen in love, and soon had Harry when they got married with the blessing of both families.
