When Lily Evans told James Potter that she wouldn’t go out with him because he was a bully, he stopped bullying people and redeemed himself. When Lily told Severus Snape that she wouldn’t go out with him because he called her a racial slur, he went on to join a racist terrorist group.
Conclusion: James Potter handled rejection much better than Severus Snape does.
I have two moods

the other is an immature 5 year old that doesn’t know how to control herself or her language or her actions
there is no inbetween
