"My Bus Conductor" is a poem by Roger McGough, a
contemporary poet who first gained recognition through a book called The
Mersey Sound, in 1967.

The poem is about a bus
conductor (in America we would call him a "bus driver") who knows that he will not live
much longer due to a diseased kidney. 

Because he knows
that his days are numbered, he begins to value small, everyday
objects:

Each
bus ticket
takes on now a different shape
and texture.
He
holds a ninepenny single
as if it were a
rose.

His behavior toward
other people also changes.  He no longer flirts with female passengers, and he is more
understanding of the poor and downtrodden:

His thin lips
have no quips

for fat factory girls
and he ignores
the drunk who
snores
and the oldman who talks to
himself.

Now that he is about
to leave the world, everything looks different to
him:

The same
old streets look different now
more distinct
as through new
glasses.
And the sky
was it ever so
blue?

In summary, the poem is
about people who look at the world differently when they know they will soon be leaving
it.  Perhaps it is asking us to try to look at the world differently even if we think we
still have a long time left to live.
