La psicología dice que las personas que avisan de que van a llegar tarde, aunque solo sean diez minutos, no lo hacen solo por puntualidad o educación, sino porque son conscientes de que unos minutos de espera pueden tener un significado diferente para la otra persona
Full story
Psychology suggests that people who notify others they will be late do more than follow rules of politeness. Even a short delay of ten minutes can be significant for the person waiting. Sending a warning shows an awareness that waiting time has a different meaning for different people. This action helps care for the time of others. It also works to reduce the uncertainty caused by a delay.
Avisar de una demora es una forma de cuidar el tiempo ajeno y reducir la incertidumbre.
