'Do I, Bertie?'
'If I were you, I'd just step straight across the street and get that one over there.'

Sippy stood for a moment in thought.
'I believe you're absolutely right,' he said at last. 'Funny I never thought of it before. You really recommend me to get that helmet?'
'I do, indeed.'
'Then I will,' said Sippy, brightening up in the most remarkable manner.
