I could see that, yeah. Although, she really doesn't like it when people try to do that. She'd have a difficult time understanding what this 'playfulness' is at first unless he made it clear, and since she tends to shy away from conflict, she'd simply not want to deal with it. I could see them getting off to a rocky start at first, though if it's been awhile since they've met they're probably on more friendly terms.

I could also see her looking at his attitude and trying to mimic it. She needs as many positive role models as she can get xD
