leaning tower of dishes

So okay, I occasionally stack dirty dishes (washing them at one shot makes more sense). You can see the stable layer of plate, another plate, plastic bowl and correlle bowl. As I was busy with other things, Arianna finished the plate of mango and decided to stack the correlle plate on top. While I think that's clever, that's just a warning for me not to leave dirty dishes, or use a plastic plate for her.
