Mind you, we don’t actually use pencils. Ever.
They are anachronistic, though perhaps we store them in the pencil drawer because of nostalgia. Or a sense that somehow they are worth more than a mere toss.
Accumulation. Without purpose.
To purge.

Great “painting” Rey!
Also great that you revealed to us how you did it. Thank you!
(I also have a cup of pencils, that are rarely used…)
