I had a passing thought this morning on why we (might) like diapers the way we do. It was new to me, though it may have occurred to others already. In any case, my "revelation" was that diapers seem to represent a sort of unconditional care. They cover the most private, intimate area of our bodies, and more importantly, they accept without complaint the absolute worst about us, literally. By taking our waste, which is the most unpleasant thing we produce, without any objection, we see them as accepting us as we are, something that not even parents truly do. They don't try to change who we are. You might be able to say almost the same thing about other inanimate objects, but somehow it's not quite the same.
Anyway, I thought I'd share that.
