It occurs to me, by this characterization of people "going around in circles"
and how one, (or I) oughtn't to feel ashamed of it, you might actually mean,
non-linear, in function and makeup--
which is a bit of a different thing, than this image of a dog chasing its tail.
I am not in any way "ashamed" of being non-linear.
(Sorry, can't think of the word right now, ironically, as a stone-mason across the way has for the last hour, if you can believe this(!!) been sawing stone with a chainsaw. He's making a nice ramp for wheelchairs.)
