Anna and the wiley toothpaste cap

I lost another toothpaste cap to the sink drain. There is that moment of "nooooooooooo" when the cap slips from my fingers and spirals around the sink, disappearing swiftly into the dark abyss of the drain. I'm reading Anna Karenina, and when Anna arrives in Moscow on the train a man kills himself by throwing himself on the tracks, and she thinks, "BAD OMEN." I had the same thought as I swapped in a red cap from a trial-sized toothpaste - BAD OMEN... what will my day hold. Since I know how the books ends, having read it before, will I befall a similar fate to the paste cap and get sucked down the drain? Nooooooooooooooo!
