Metaphore.

I was sitting at the bus stop
just a block away
only a couple inches away
from an intersection
cars waiting impatiently
to go to their next destination
i know by heart
which light will pop to green first
First the cars from the right
may go
others get more impatient
will it be my turn next?
More cars line up
Now the cars from the right may go
Then the ones on the other side of the street
then
finally
you.
The light switches to red again
Cars line up again
Waiting impatiently
to go their own way.
As time goes by
this pattern
repeats itself.
The same
over and over again
if you listen closely
the only difference you hear
are the noises of the cars.
But from the outside
it's the same thing
over and over again.

Realizing this
I got a little scared
What if this intersection
is a metaphore
for life?
