At the auto show on Monday, the Volvo display was one of the only areas on the show floor with any seating (aside from sitting in the cars themselves). A group of cream-colored leather couches (possibly Swedish, probably not from IKEA) was arranged in a rectangle, and a couple of families were taking a break there.
As we passed by, a young boy of perhaps four jumped up from sitting alongside his parents and started walking across the seating surface of one of the sofas. I didn't see the reaction of either parent, but the mother called the child's name several times, scoldingly but with little sense of threat or consequence behind it, in a vain attempt to get him to stop.
I then heard her say, perhaps to her husband, another parent, or possibly even to herself, "This is why we don't have white furniture at home." I couldn't help myself: we weren't that close, but loudly enough so that it was within the realm of possibility that the parents heard me, I said to my friend, "This is why I don't have children."
