Nor concrete, nor rebar.

Palm trunk.  Nature and humans do similar things with texture, even if inadvertently.

That reminds me, is ‘advertent’  the opposite of ‘inadvertent?’  I don’t think so, as my software editor here underlined that in red.  Off to Google I go to check…aha!  ‘Advertent’ is indeed an antonym of an older meaning of ‘inadvertent’  — and it means ‘attentive’ or ‘heedful.’  Oooh, ‘heedful’ — that’s a great word.  Not quite the same as ‘mindful’ — a little more cautionary?

From palm tree trunks to ‘heedful’ — that’s one of the reasons I like doing this blog!
