5.2.1-5 Do my work colleagues or my fellow students belong to the ‘personal area’ within the meaning of private use in the personal sphere or in a private circle?

Generally speaking, no, because the ‘personal area’ also necessitates that there be a close personal relationship between the people concerned. This is not the case with work colleagues or fellow students. However, something else can result when particular work colleagues or fellow students have a closer relationship with each other than the usual employment or training relationship (e.g. a close friendship develops between two or three students, or two students move into shared accommodation together).
