The very concept of a soul mate sounds hopelessly hippie and '60s. But for some romantics, there is one person out there and they won't settle for less. Perhaps they imagine when The One shows up, a rainbow will suddenly appear and a unicorn will jump over it holding a bouquet of roses. (Or something like that.)
Even the rather dry philosopher Plato imagined that at one point, people might have been divided in two and that they spend the rest of their lives looking for their other half.
There are pragmatics who believe you should, in the words of Crosby Stills Nash & Young, "Love the one you're with," and then there are the hopeless romantics who may pass up perfectly wonderful prospects in order to see that unicorn jumping over the rainbow. Do you believe in the idea of a soul mate? Or do you think it's corny and unrealistic?
