Shaking his head in bemusement, Bart smiled. "I'm fine, sweetie." As soon as the words were out of his mouth, he had a mini-panic attack. Had he ever called her that before? He didn't think so, but they were friends a long time ago, for him. There were times when it still felt like he was an adult talking to a teenager, and not a boy of indeterminate age talking to a teenage girl. He didn't want to sound like he was moving in on Tim's girl, either. He had only just come back, alienating his friends would not be a wise first move.
