This sign in a Denmark cobbled street supposedly warns ladies wearing high-heel shoes not to catch them in the cracks. We were okay with this until we wondered how to avoid this happening in the traffic. And why only lady’s shoes (unless some local lads have gay old times in drag)? The plot thickens when you realize there’s no red line through the picture.
So this could not be what you think. Do you suppose students have high-heel-breaking competitions? We do know most things happen in Denmark and we don’t see why not this too.
