ABSTRACT
It is not generally considered polite to interrupt. However, etiquette is not simply about politeness but also appropriateness. us, while etiquette dictates that it is inappropriate, counterproductive, or even dangerous to interrupt someone with irrelevant information in the middle of a critical task requiring great concentration, it also allows that it is appropriate and necessary to interrupt with crucial information. For example, it is inappropriate to interrupt an airline pilot during landing with the baseball score, but entirely appropriate to interrupt with the information that the landing gear has malfunctioned.
