Speaking of explicit lyrics, the Stones nail it in Satisfaction when they sing about “…some useless information, Supposed to fire my imagination”.
That got me thinking about explicit and implicit information. Explicit useless info is the .00 cents in the $389,900.00 house listing. It’s the ‘left’ and ‘right’ identifiers for two-subject captions.
Explicit helpful info is the last exit before toll, last exit before construction, last gas for next 100 miles/km.
