Lots to do this morning and posting here wasn't on the list.

Unsure, as I was, how to spell 'rhus' ( was, it, I wondered, two 's's or one?) I did a quick Google search and found that this beautiful tree has sap which can, in some people, causes a nasty allergic reaction . I learned, too, that in some parts of the world it is regarded as a noxious weed and landowners are obliged to clear it.
So it seems to be that the tree is a useful metaphor in itself. For how we process things through our filters to make sense of the world and the fact that we can, if we choose, change those filters and thus our view of the world.
And there's more (of course!). Most of the year the rhus is an unremarkable tree-bush that adds, for me, no visual - or other - appeal to my garden. And yet, as I was reminded this morning, that same tree has great beauty within it - just waiting for the chance to shine. Another metaphor, perhaps? I think so.
