I have attached my short piece - about metaphors -  to this, as I don't seem to be able to get on to the blog site at the moment -
Apologies for clogging up your inboxes, I was hoping to put it on the blog so people could look if they wanted to, rather than inflict it on everyone.
A number of you have expressed an interest so I am doing it this way.
