You say to brick, ‘What do you want, brick?’
and brick says to you, ‘I like an ARCH.’
and you say to brick, ‘Look, I want one too, but arches are expensive and I can use a concrete lintel over you, over an opening.’
and then you say, ‘What do you think of that, brick?’
brick says, ‘I like an ARCH.’
