Screenwalking has become extremely common. The screenwalker resembles K, back more or less straight, one leg in front of the other, arm held at differing degrees of upright, screen unlocked. They are kings and queens of self-absorption. K describes their daily encounter with non-screenies. The screenwalker steps in a more or less straight line as the non-screenwalker curves, or makes a rapid ninety degrees to avoid collision with the obvious, or rather oblivious. K-Lanes may have to be introduced on footpaths and public concourses to remedy this daily traffic, though will screenwalkers remember to keep inside the dedicated K lines?
