Have you noticed anything significant about persons having planets or placements on your South Node?

I have SN conj Sun,Ur,Mercury and Jupiter and I know a male with Sun conj Ur,Mars and Venus. We are both Cancers and the Sun and Ur are at the same degree in Cancer. We had an instant connection,but not Love on my part,he reminds me of an annoying little brother or a sibling that competes with me and constantly tries to impress me at the same time....90 percent of the time I have to swat him like a fly...so annoying and always around me,but yet he is most useful to me .
