Why not?? Girls can have all the fun. Gone are the days when girls had restrictions and apprehensions. In the world of changing trends, girls are coming out more and more. Now they are equally educated, equally placed and earning equal pay.
The definition of fun may change a little bit here and there when it comes to girls and boys, but pretty much girls are getting bolder and reaching out to all the fun they can have. Women are equally working and earning. This financial freedom is encouraging girls to come out and live life on their own terms.
