I wonder how much the current concept of a "friend" is the by product of 20th century media. Much like adolescence was not what we know it as before mid-20th century, I can't help but feel that the role of friend (especially adult friend) was largely shaped by sitcoms. I think the expectation that you would have adult friends ala Friends (the show) is largely manufactured and giving people false expectations.
