I'm A Terrible Person

I'm a terrible person I'm a terrible person I'm a terrible person Cause I've made up my mind I'm a terrible person Cause I've led her on and I'm the only one who knows what I've done to her, oh yeah I'm much smarter now I won't tell her friends before her Oh I'm afraid It's gonna be a bad day come Sunday I'm a horrible person I read her diary I'm not to be trusted I told all of her secrets To all the guys in town They all laugh and slap me five, oh yeah Luckily she doesn't have dirt on me Cause I'm the cleanest guy Oh I'm so afraid It's gonna be a bad day come Sunday I don't think I'll ever be sorry No I'm not sorry for a thing I've done And I don't think I'll ever wake up lonely Cause having her around Wasn't all that special It's gonna be a bad day come Sunday
