Could she be giving me a hint?

Could she be giving me a hint?

I know a woman who works in admin, enrollment of new trainees and class scheduling in the driving school i'm attending. when I ask her for information about the lessons or other school matters and she finishes helping me (she's usually siting or standing behind a counter), we end up staying there looking at each other in the eyes for a few moments until I thank her and say goodbye, she doesn't disengages ( ex: doesn't asks if that's all I need, doesn't say goodbye).

It's not the first time it happens in fact we end up like this every time I talk to her (I've only talked to her about school matters). I don't mind it but I just find it a bit unusual. I'm attracted to her and I keep wondering if that could mean she has some interest in me.

Could she be giving me a hint?
