Some people don't like to give their location over the internet to random strangers. For a general idea of where one would live, a common response would be "the 610", the area code for where I live. It includes a vast majority of the South-east portion of PA.
I live in the 610.
I didn't want to tell *insert epal's name here* where I live, so I told him I live in the 610.
Under "Hometown" on MySpace, it says that I live in the 610.
