Severus was not sure to be happy or sad, the chance he would ever be able to take Lily to a ball was very slim. He was not from a rich pureblood family, he might be a Slytherin and he knew rich pureblood wizards and witches but that was not the same. He knew that it would be a huge miracle if he ever got an invitation to a real ball.
"I am sure you will go to one, Lily." Someone as pretty as Lily would probably be able to go to lots of balls, someone would sweep her off her feet and take her and she would be the belle of the ball.
