Bold look of a girl
Boldness is not a sin. It's just a way of living. You can choose your way to live. You can decide if you want to be shy, reserved, bold or whatever you like.
And you can't really know by someone's behaviour if she's outgoing or not. Maybe she acts reserved in front of some people but is actually bold in front of her close ones.
So, rather than presuming something. It's better you get to know a girl then evaluate. And I am still wondering what you're going to do with the boldness of a girl.
