Abstract
Talking on the phone is usually a private activity, but it becomes a public activity when using a cellphone in certain spaces. Unlike a traditional payphone in public, cellphones do not have privacy booths. Therefore, the ways in which people respond to cellphone calls in public spaces provide markers for social topographical space. In this study I explore how cellphone users negotiate privacy when using cellphones in public space and how those within the proximity of the caller negotiate space in response to these callers. Based on a year-long study involving observation fieldwork and in-depth interviews, I discuss the flexibility with which people constantly negotiate their private and public sense of self when using and responding to cellphones in public spaces.
