A woman gets out of bed on an ordinary morning and wants to have breakfast, but... everything in her house is made of ceramics.
A woman gets out of bed and sits down in her pajamas for breakfast. How delicious, a bowl of cornflakes. But with the first bite, she nearly breaks her teeth. What’s going on? The cornflakes are made of ceramics. Maybe a sip of milk then. But why won’t it pour from the glass? It’s also a block of ceramics, just like the rest of the house and all the food. Tough luck.
