»In which we recall the darling buds of May

I had more than enough time today while waiting (from 1706 until 1718, at 8th and Market), so a sonnet rather than a haiku:

Shall I compare thee to a MUNI bus?
Thou are more timely and more fleet-of-foot:
Rough traffic shakes the snarling Boulevard,
And rush-hour's flight hath all too long a wait:
Sometime too clean the bus rarely arrives,
And often is the ventilation stifl'd;
And year by year our tariffs incline,
By chance or traffic's changing course untrimm'd;
But thy infernal wait shall not fade
Nor lose possession of that fare thou owerst;
But shall Death brag thou wander'st in his shade,
When in eternal lines to time thou growest:
   So long as men can breathe or eyes can see,
   So long MUNI shrugs its responsibility.

Apologies to the bard. This is doggerel, not a sonnet.
