Nail Polish Craziness O.o

Last night I heard my sister in her room talking to her friend Jenna about... Nail Polish?! Of all things, IT WAS NAIL POLISH! It was the types of blue nail polish that they own in particular though, which makes no sense. Usually Lisa is a pretty cool big sister, but she gets weird sometimes, especially when she talks to her friends... I wanted to list all the types of blue nail polish that she owns in my LJ, so I wrote them down as she listed them :) (I think I missed a few though :\)
Baby blue, Midnight blue, Periwinkle, Green Blue, Blue Green, Cerulean, Blue Chrome, Manatee, Aqua, Sparkling Blue, Sapphire, Ice Blue, Blue Bell, Turquoise, Azure, Silver blue, Steel Blue, Royal Blue, Indigo, Blue Violet dark, Denim, Cadet Blue, Neon Blue.
In my opinion, that's too much blue nail polish.... Why any company would make all of this blue for the sake of painting fingernails and toenails is beyond me O.o
