Why bother?

Walking up from the train station this morning I was unfortunate enough to overhear this complete waste of space and energy. It was one of those inane bollocks 'can't stop because i'm so damn important and busy' conversations so it went like this [verbatim minus stage directions]:

Scene 1: A man and woman cross paths walking in opposite directions.

Woman [walking full speed past man]: 'Hi!'

Man [walking full speed past woman]: 'Hi'

Woman: 'How are you?'

Man: 'Good'

Woman: 'Good'

Man: 'And you?'

Woman: 'Good'

Man: 'Good'.

Man and woman exit stage right and left at full speed.
