A business piece in the New York Times lightheartedly highlights a very real challenge facing freelancers: working alone at home.  A journalist, Abby Ellin, writes about how she came to rely on the voice of her answering machine for company as it screened calls. Ellin had a revelation after her answering machine's battery died, leaving her without its voice for two days: "That's when I knew I was craving a full-time job in a real office. It wasn’t about money or health insurance or paid vacations, though those are certainly nice perks; it was about sanity and recognizing that it’s O.K. to be just like everyone else." Does the isolation of working at home ever get to you?  How do you deal with it?
