Freddy: Freddy had been stalking you again, so he got an earful from you about how creepy that is. He didn't care, he just kept on stalking you.

Jason: Jason had killed one of your male friends because he thought your friend was a threat to your relationship. You told Jason that he was just a friend, and you avoided Jason for a few days after so you could mourn your friend in peace.

Michael: You knew Michael was protective of you, but you didn't think he'd go to the extreme of following you around 24/7. You thought it was creepy that he did that, and so he got an earful when he got home.

Leatherface: Thomas is too adorable that you just can't stay mad at him.

Hannibal: You were good friends with one of your co workers, but Hannibal thought he was trying to steal you from him. Needless to say, your co worker friend was the main dish at one of Hannibal's dinner parties. You didn't dare show your anger in fear of what he'd do to you, but you got to vent your anger and sorrow on a punching bag. Poor punching bag...

Norman: Norman never did anything that he knew would upset you.

Ghostface: Ghostface stalked you near constantly, once you found out. He got an earful. That didn't make him stop stalking you though.

Jack: Your best male friend came for a visit to see if you were okay. Needless to say, he got an axe to the stomach and chest. Jack managed to dispose of the corpse without you seeing it. But you saw the blood.

Once you found out you stayed away from Jack so you could mourn in peace.

Pennywise: You went to school as normal, only to find every male except for male teachers were missing. You knew why they were missing but didn't say anything. Who would believe the story that an urban legend killed those guys over you?

When you got home, you made sure Penny knew you were upset about what he had done. It was still justified in his mind though.
