It sounds like she was being a bit playful or sarcastic with her comment. It's possible she was trying to compliment you in an indirect way, or maybe she was joking about her own standards. If you're interested in her, you could take it as an opportunity to engage in lighthearted conversation. If the comment bothered you, though, it’s totally valid to address it or just let it go. How did you feel about what she said?
