This chapter addresses the issue of boundaries: how are the boundaries established between one site where a particular kind of affect is being fostered and another site where some other affect is either encouraged or where the affect fostered by the former site is no longer a relevant concern? The chapter begins with a brief consideration of various attempts to demarcate specific sites as ‘friendly’. This gives a sense of what the semiotics of conviviality might look like. The latter half of the chapter comprises a detailed case study of a ‘dementia-friendly’ neighborhood in Singapore.
