A scene goes haywire

She had a cone of vanilla,
her flame red tongue darting out
every time she savoured it,
And he had a scoop of strawberry
which he devoured leisurely
in between her whispers and giggles.

The man at the counter bided his time.
puffing on a cigar and stroking his beard.
The channel poured forth
a soothing sonata.
I went on sipping my lemonade.
A sense of ‘dejavu’ getting into me.

The cat saunters in as if from nowhere
I see it getting under their table
The girl lets out a shriek and jumps up
the boy gets up with a start
the man drops his cigar.
I have forgotten my lines.
