Out-of-balance relationships provide a particularly needling kind of heartbreak. Doesn’t matter what arena the relationship plays in — romantic, friendship, family, celebrity idolizing — it’s all the same twinge of suffering.

It’s all in the unreturned glance, the message left unanswered. Having been on both sides of the fence doesn’t make it any easier, either.
