I can't say that I think it would be a good thing that would work out well
They'd probably 'stab you in the back' (not literally), whilst you were elsewhere, but whilst you were talking in a group to your face pretend that they are your best friend!
Not all women are like this obviously, but there are plenty of women out there who are, especially when grouped together in large numbers!
Let's hope we never have to live through this 'world of women only!
