Seriously though. James Potter was a much better man than Severus Snape. Whereas James bullied Snape while they were kids and then grew out of it, Snape used his position of power at Hogwarts to bully children.
The real reason Harry Potter's mom was the best potions student. (i love the look on severus's face)-I like to think that Lily was great at potions on her own and Snape just perfected his potions ability as a way to impress her.
