She was young, but he couldn't really say he'd ever seen her act like it ... tonight being the closest. Her blushing had been well worth seeing.
When she said she'd had a bad experience with a boy he'd immediately wanted to ask what sort of bad experience, but even with his own curiosity he knew that was crossing a line. With her hand still in his, he took a step back and gently spun her around with a chuckle. "I do hope you don't judge all of us based on the one," he commented, pulling her back to settle his hand back on her waist.
