Certainty of Uncertainty?

For those who like certainty,

Scanning the streets of Baltimore,

At 5:45 on a Tuesday morning,

You will find two runners out and about.

The certainty is in seeing these two

Almost every Tuesday

For the last six years.

The course the two runners follow

Is almost as certain.

Most weeks winding up and down familiar hills

Through familiar neighborhoods

With certain and familiar smells.

Smells like the bread from the industrial bakery

On the south side of the course.

But one morning,

The runners missed the smell of bread,

And instead a few blocks later smelled meat.

There was no doubt it was from a pig,

But the regular runners debated

Whether it was ham or sausage.

After about a block of discussion

The consensus was ham,

Maybe to be served with pancakes or French toast

At a local breakfast joint.

While that was just a small part

Of the run and discussion that morning,

The uncertainty led to interesting discussion

With certainty.

       With how much certainty

       Do other instances of uncertainty

Create interesting conversations or connections?
