Dismissive???

Why was Mindy initially so dismissive when Dave suggested they become a crime fighting team? She said "I play NFL, you play Pee-Wee" which seems pretty short-sighted considering he rescued her at the end of the first film via jet-pack/Gatling gun combo, killed the "final boss" with a bazooka, and literally picked her up in his arms and flew her to safety. It just seemed like the major strides Kick-Ass took in the first film were tossed aside and he was just some scrub wannabe again to start this chapter.
