Well said. Sounds like you experienced it too. I agree that I made assumptions that I shouldn’t have about asking if I could visit them this summer. I also agree with you that hindsight is always 20/20. She and I had nothing in common but the Facebook group.
A good lesson for me since it’s really hard to get to know someone online for whom they truly are. This is why I just want to meet people offline and socialize in person. The risks of being incompatible are less when you socialize in person. That makes it easier to suss out whether or not the other person and I would be a good fit as friends.
