And should I then presume?

From Eliot's The Love Song of J. Alfred Prufrock -

There will be time, there will be time

To prepare a face to meet the faces that you meet;

There will be time to murder and create,

And time for all the works and days of hands

That lift and drop a question on your plate;

Time for you and time for me,

And time yet for a hundred indecisions,

And for a hundred visions and revisions,

Before the taking of a toast and tea.

Happy (American) Labo(u)r Day, people!

And here's a song for you.
