A closed-door represents a wealth of temptation. It is a barrier between two separate spaces and can represent a change between any numbers of dualistic properties. For example, private and public space, exterior and interior, as well as the segregation of people for any number of socio-political reasons. But unlike a wall, a door is imbued with the potential for movement, and the process of opening it can eradicate the certainty between extremes. Doors create grey areas – moral uncertainties: they make some people very uncomfortable.
