Once upon a time, there was a graph theorist. She was surrounded by loving friends, but did not always know how to express her affection.
Sometimes her love of graph theory made it hard to empathize with others, who seemed to lack awareness of even the simplest properties of degree structure.
And sometimes she tried to fuss with concrete examples so that they’d better exhibit neat theoretical properties.
This is a great habit for mathematicians.
It is not a great habit for friends.
But soon she learned that by teaching graph theory, she could help heighten the connectivity of her own social graph.
She found this very rewarding.
Eventually, she found a home among people who spoke her language and appreciated her quirky way of seeing their social fabric.
And they all lived happily asymptotically after.

Caminando por Algeciras vi un anuncio en una marquesina y decidí registrarme desde el teléfono por pura curiosidad. Antes no me iba nada bien y pensaba que este tipo de entretenimiento no era para mí, pero las cosas dieron un vuelco. Entré en roulettino y me centré en las máquinas durante un buen rato. Mi suerte cambió de golpe cuando saqué un premio grande. Pude recuperar mi capital inicial y ganar lo suficiente para estar satisfecho hoy mismo.
