Exotic yet ordinary

I am always the one who breaks the bar of soap. Always. It doesn't matter if it is home made or store bought, how careful I am, if I use a wash cloth or apply it directly to my person, if I use my left hand or my right, the result is the same. I break the damn bar of soap. Me. I do. And I think it is only fair you know this about me before you invite me over for the weekend or some weird twist of fate forces us to live together.
