This article is exactly what I needed to read.
My three best friends are people that I connected to in a very short amount of time and whom I do not see regularly (we live in different countries) but our connection was so immediate and so strong that I know we are souls who recognized each other immediately.
They are of the opposite sex and my mother asked me, after hearing me go on about them, "are any of them spouse material?" I struggled to explain that no, we are just like souls, not necessarily with marriage as an end.
It's also synchronistic that Erin wrote that cells that recognize each other say: "what's the haps?" and that's the phrase we use to greet each other. Wild!
