Who are the two brothers who live on opposite sides of the road yet never see each other?

Why this works

This riddle plays on the idea of "brothers" as a metaphor for eyes, which are typically found in pairs. The phrase "live on opposite sides of the road" cleverly refers to how our eyes are positioned on either side of our nose, resembling two brothers on a road. The twist is that, despite being so close, they can never see each other, since each eye can only look outward and not at the other. It's a fun way to personify our features and highlight their unique arrangement!
