An uninvited verbal intervention regarding a strangers' behavior around
issues such as sustainability, global awareness, or
personal liberation. 'Kaths' are usually gentle, but can be forceful. Typically, 'Kaths' immediately annoy, but they are offered - often courageously, often ridiculously - in the hope that the more reflective come to appreciate their
logic.
A mild 'Kath': "Please
don't litter - I
don't want to live in your wastebasket".
More forceful: "Take off the veil!", as, say, in 35C heat, one peddles past a burka wearer walking well behind a
summer-casual-dressed male on the bike path.
