Let me tell you a story… other than me being a CD, I’m an immigrant to the US (legal). When we first got here, it wasn’t easy to find others coming from Mexico at the same places we would go to eat, shop, etc.
Every now and then we ran into some others. We would talk and sometimes we would agree to met again with them.
Well, out from 20 or so of such encounters, we finally met another couple with similar cultural and social-economic background, and ended up establishing a lasting friendship with them.
Having only the same original nationality was no warranty we would hit it off with them. In other words, we would only become friends with others if we could have become friends back in Mexico.
Just because you met other CD there is no certainty you would end up becoming great friends. It happens, but there has to be more than the dressing.
