QUOTE : As far as Aunty Lee was concerned, people ought to go through the ideas they carried around in their heads as regularly as they turned out their store cupboards. No matter how wisely you shopped, there would be things in the depths that were past their expiration dates or gone damp and moldy---or that has been picked up on impulse and were no longer relevant. Aunty Lee believed everything inside a head or cupboard could affect everything else in it by going bad or just taking up more space than it was worth.
