Importantly, the Spanish fellow you mentioned took some time to display some of these emotional signs. Too often, though, people tend to make snap judgments. It seems that in the online dating world, especially, people do this. After meeting or talking with you a couple of times, and seemingly enjoying it, they just move on. Often without any further communication. It can take time to build that emotional connection, but I think people are actually afraid of real emotional connection. Too many serious implications.
