I once had a similar discussion about a phrase that was something like "smooth soft stone," describing a surface someone was walking on. It's a straightforward description of a sensation: if you're walking on a stone surface in bare feet, smooth stone feels much softer than rough stone. If you know how it feels, the phrase sounds perfectly smooth and natural, but if you've never experienced it, or don't remember experiencing it as a child, you might think the phrase is meant to sound jarring paradoxical, instead of gently referencing a paradox doesn't even feel paradoxical to us because it agrees with how we perceive the world.
