Why some wanderers shy others not

[Spaced]

I think it makes sense that wanderers would be shy, after all 3rd density is THE density of social interaction. I imagine the higher you go density wise the less social interaction there is, especially because more and more we will just KNOW what others are thinking and so have no real need for conversation. Getting into the swing of this social maelstrom of a planet after experiencing other densities would most certainly be disorienting.
