Heels.

The sound of heels.

As he just walks out of a pretentious presentation.

In condescension.

Ensuring that the heels make a noise and the audience (we, the people) notices someone walking out.

As if sun is guilty of violating societal norms — by hiding behind the clouds.

Do we hear the noise when something walks out of our mind?

An email? An instance?

Do we check what violates the norms — an Entry — its Stay, or the Exit?

Particularly when we raise something completely out-of-context — like the untimely patch of clouds.

Assume that the speaker had won a keynote slot because it has sponsored the stage.

The catch is to be watchful for both — the sponsors and the heels.
