I hate it when ketchup turns on me, and magically splits into grose water and a lumpy mess of tomatoes. When you put that on your pasta you always have to face the inconvenient choice of eating it with water-ketchup or making a new plate.
Also i'm not very fond of the neverending dust production in my apartment, but if you are like me, lazy, i guess you can learn to accept it and make friends with it instead of cleaning it away.
peace.
