New York rent is a killer right (edit: actually their place looks outer suburban at least)? Doesn't surprise me. Along with essentially everyone I know in my area I moved out at 18 (a few younger, but their parents had to sign off on them being unable to live in the same house), but as housing prices/rent has gone up that age has been increasing. Still, nothing like friends from Japan, Hong Kong and Singapore who apparently had no intention of moving out as young adults (little wonder they were sent to university in Australia).
