Brothers in a Medieval Castle

I had a dream.

In it, two brothers are living in a medieval castle made of brown stones on the edge of a precipice. They have contrasting characters, but they are very close to each other.

The younger brother is a short handsome boy. He is a genius in mathematics, and is always reading old parchment books. But he isn't a professional mathematician, and has never presented any paper. He discovers new formulas by himself just for fun.

The elder brother is a tall, dull guy. He isn't interested in any study or book at all, and he is always looking out to the sea. He hits a bell on the top of the castle at twelve o'clock. But he can’t count how many times he hit the bell, sometimes he hits it thirteen times and other times eleven times.

The younger brother helps the elder brother to count to twelve. They shout together,

one, two, three, four, five, six, seven, eight, nine, ten, eleven, and twelve!

And then they are very satisfied. The younger brother starts to read a mathematics book, and the elder brother is just looking at the sea.
