I teach several kids how to play a musical instrument and after recently keeping track of their birthdates I noticed a pattern emerging.

There seems to be quite a few that have their north node in Virgo/south in Pisces while I have my north node in Pisces/south in Virgo.

Does any one have an qpinion on this?

My feeling is that is possibly a karmic connection and also why I relate to them easily.

 Thanks in advance to any one that answers

"My feeling is that is possibly a karmic connection and also why I relate to them easily."

I think you're right! A friend of mine from college introduced me (online) to one of her professors (who I had never met while I was at school there) who has studied astrology all his life, and we became e-pals for a little while, chatting about astrology, poetry and life...we discovered our nodes were reversed (he had north in Aquarius, while I have the north node in Leo). 

There was totally a karmic connection with us. Too much synchronicity!
