I find that interesting both as an observation and a statement. It's added an extra facet to my perspectives on the subject, thanks.
At the same time though it reinforces the thought (in my own mind) that 'evergreen', as I mentioned in an earlier post, is actually 'deciduous', ie, it is 'seasonal'.
This 'season' is not on a fixed cycle though. My own mental imagery has always seen these type of things as a lighthouse of sorts - it shines and lights up things for a period of time but continues sweeping round to illuminate whatever is next in its sights.
Eventually it will come full circle and bring to our attention something that has been hidden in darkness for sometime. When lit up once again it is as if that 'something' had never disappeared from our sights.
I doubt that will make any sense to anyone, but it does to me :-)
