How is it that grass has girl summoning powers? Is this power still present if the grass is ground to a fine white powder, combined with other ingredients and baked into a loaf- or baguette-shaped object?
I'm glad that I live in the present day rather than the primitive times when I would have had to interact with other people face-to-face in order to survive. I can't even imagine how difficult that must have been.
(How did people satisfy their sexual urges back then? Did they have to convince another person to pose naked every time they wanted to masturbate?)
Imagination (most important). Books, drawings. Also you can't miss what you don't know exists. People were probably content with what they had. Or just wanted things that were around them.
