don’t draw children naked? Is that difficult?

To draw from implies accumulation...difficult/differ implies separation. Nature separates; artifice accumulates.

That's also why those who accumulate (wanted temptation) withdraw into nakedness...hence wanting to separate cloth from body aka guilt from innocence aka adult from child.

perhaps

Aka by (per) happenstance (haps) aka by chance (artifical) as oppose to as choice (natural).
