@PUNKEY,
You probably spooked her.
In much of the world, staring is rude, often creepy. If you know someone, it can be good.
I gather from posts on a2k that a lot of guys in India do this to some girl.
I'm not from there, so I don't know how generally it is accepted there.
Maybe guys like it and women don't.
You may not be from India - I'm just saying that we get a lot of questions about this on a2k from starers and they are often from men or boys from India.
