Yup. She sounds fairly modest, and we women tend to exaggerate how we see ourselves. It might be one of those things where she wants to approach the subject carefully, because it really IS an awkward subject for women to talk about. Using a internet phrase kinda lowers the tension around tough topics for some people I guess.
Appreciate the fact she told you at all though. Sounds like she's opening up to you, and putting trust in you. Either way, don't lie to her about what you feel. Keep us posted =D
