@[email protected]📖 Me gusta juzgar los libros por su portada y darme cuenta de lo equivocado que estaba al leerlos.
📚 Mis géneros favoritos son la Fantasía y el Terror, pero leo un poquito de todo.
✒️ De vez en cuando romantizo mi vida escribiendo.
Uso Linux y siempre que puedo busco alternativas Open Source, porque a este paso nos van a cobrar una subscripción hasta por encender el móvil.

What Orwell feared were those who would ban books.
What Huxley feared was that there would be no one who wanted to read one.
