Vigil- An event or a period of time when a person or group stays in a place and quietly waits, prays, etc., especially at night
“The honor of his art forbade it. Naturally, none of the watchers understood that. Sometimes there were nightly groups of watchers who carried out their vigil very laxly, deliberately sitting together in a distant corner and putting all their attention into playing cards there, clearly intending to allow the hunger artist a small refreshment, which, according to their way of thinking, he could get from some secret supplies.” -The Hunger Artist
In this situation a group of people come by and fail to understand why the hunger artist is the way he is, trying to spare some refreshments and attention. The word perfectly describes this scenario as watchers look on to the artist, despite the signals given that means that their actions are unwelcomed.
