Right now, there is no official word - people just speculating on the reason for the tattoo. It appears that Rihanna is a fan of guns (or likes how they look) - she's been seen wearing a necklace with gun pendants on it. I don't think there has to be a reason - maybe she just thought it looked good.
She thinks guns are trendy and so she got the tattoo. Really nothing deep about it.
I'm not really sure about the first part of your question. Hope she doesn't think that little ole gun is gonna scare Chris away! As for whether she is over him or not, I heard they were moving in together and according to this picture she is back to her glam self.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
