Handedness

Huginn: It is amusing to see the way they handle left-clawedness. Because the left-clawed have a competitive advantage in all areas, they create obstacles like spiral staircases, scissors and other bedevilments to make it hard for the left-clawed to use that advantage.

Muninn: But their chemistry and their brains don't match, where handedness is concerned. Of course, they remember on their left sides and forget on their right...

H: Their eyes are crossed.

M: That explains it then — they must think that the left are right.

H: Shouldn't that be "the left is right"?

M: Memory means what memory says.
