I was attending a business conference in Michigan recently and started a conversation with a lady who sat next to me at the hotel bar. Somehow the conversation turned and I commented about being raised a JW. Found out she was also a born in now out witness. There was a great connection and immediate bond. However it is somewhat artificial. We both were excited due to a shared upbringing but that is not the basis for a 'hook up" or relationship. It is an artificial connection.
It can be a good starting point but really shouldn't be the foundation of any kind of relationship beyond an acquaintance with a shared background. Anything more needs to be deeper.
