Ghost hated how optimistic and upbeat you always were, it rubbed him the wrong way. He'd often talked shit about you and just generally tried to bring you down.

"You wanna hurt me? Go right ahead if it makes you feel any better, I'm an easy target...yeah, you're right I talk too much...but I also listen too much, I could be a cold hearted cynic like you...but I don't like to hurt people's feelings, but you think what you want about me, I'm not changing....I like- I like me," you snap at him.
