Parallel Lines

Parallel lines have a lot in common, but they never meet. Ever. You might think that's sad. But every other pair of lines meets once and then drifts apart forever

While out walking early this evening, I was watching one of my Amish neighbors arranging his hayfield into long lines, preparing them for baling and it struck me as interesting how my field of vision was just dominated by parallel lines. 
Lines of grass, lines of stone, lines of asphalt. Will they eventually meet and then slowly drift apart; or simply ramble on, silent pseudo-partners... always close but never quite connecting?
