Twin souls? You mean everyone has their other half somewhere in the world? Like in all those romantic comedies?

@nibir It's a little more complicated than in the movies. A twin soul is not just a perfect match, but more importantly a deep connection at the soul level. It's as if you've known each other forever, as if you were two parts of the same whole.

It's best not to look for or see it in every new potential partner or current partner.
