Sweet woman?... Loool! Not me! I never did date sweet woman! Because sweet is a little bit lie... It's hiding your feelings to show you are sweet... But truth is: nobody is really sweet, not always... Everybody have bad side.
I prefer you are yourself, good in some part, bad in some part... but a TRUE person, not "lie to be sweet"... xD
And I don't know what French guys like, me I am one French guy but I think other French guys have other opinions... But I don't care because it's not my opinion! :)
