What makes a kindred spirit?

If you've ever seen Anne of Green Gables you'll know what I'm talking about when I refer to "Kindred spirits". Kindred spirits are people that you connect with on a deeper level than just basic intellectual and emotional interaction. They are one who you have a unique spiritual connection with. That feeling that somehow you must have known them in a previous life and you've finally reunited. There have always been those kindred spirits I have found throughout my life that have had a unique affect on me and my development as a person. People that I will never forget even though the ability to communicate becomes difficult as we go our separate ways through life. Some of these people that I speak of, to remain nameless, I did not seek after their friendship. It was almost as God placed them there on purpose because he knew I needed them. I've always wondered why we don't connect with everyone like that. What is it that makes the "kindred spirit" connection happen? Could it really be that we knew in the pre-existence that somehow our paths would cross in this earthly life? Or, is that special connection a way that God let's us know he's gifted us to each other for a specific reason. This is getting a little deeper than I intended. But it's a little glimpse into my mind as I've "scanned" the crowd at church and playgroup for the past couple of weeks in our new home wondering who that special person may be that was meant for me, or I for them. And I can't help but mourn the loss of those "Kindred Spirits" that I left most recently in Indiana. So, here's to you all! All you wonderful people that have made a difference in my life! I'll never forget what you have done for me.
