Evening Blueprint Inspection

I noticed a colourful fold-out subway map lying on the lower shelf of the bookcase, completely spread open like a grand construction blueprint! I trotted right over, gripping my white mug tight, and began following the bold yellow and orange transit lines across the smooth paper. At a major junction where three lines crossed, I found a tiny loose plastic washer resting flat. It looked exactly like a round foundation pad waiting for placement, so I firmly nudged it with both hands until it sat perfectly centred on the intersection mark. Looking over the whole glowing network all lined up and ready for tomorrow's commuters makes the whole evening feel completely on track!
