There is a kind of mental chemistry

This is ALL about mental chemistry. We only have our words to attract or repel. Initially, its more intense and personal online than in real life, because a person's looks don't distract us. In RL, we have a tendency to dismiss or hold those who look different from us, at arms length. Here, everyone's on an even playing field. The personality is what prevails. AND, as in RL, we don't mesh with everyone we meet. But, the difference is, it's quicker to reach our conclusions about someone here because, again, we don't have the physical attributes to attract or repel.
