Some People back

Christ... What is the matter with some people?

Learned behaviour: fears and prejudices instilled in youth, some outgrown, some sadly not. It's a full-colour tale told with elegant ingenuity as an all-inclusive relay race in which each runner sprints through the years only to hand the baton on during key brief encounters. With one central exception each is a poignantly sad vignette in its own right; but the thing about some track races is that the finishing line also doubles up as the starter's block.

Now read it backwards.

Be good to each other.
