Friends At Work

Why do people we work with think we should also be friends?  Why can't the relationship remain focused on the job?  Is it, I wonder, a more universal phenomenon or is it more common here, an American experience?  Why are we so insecure that the prospect of work being a working relationship does not meet the perceived entitlement?  Does the value of working together diminish if we cannot carry it beyond into friendship, and why is that the case?
