STEP FASTER, PLEASE.

 Of all most aggravating¹ things,

If you are hot in haste,

Is to have a man in front of you

With half a day to waste.

There is this one thing that justifies²

The man in the foremost place:

The fact that he is the man in front,

The leader of the race.

But, for Heaven’s sake, if you are ahead,

Don’t dawdle³ at your ease!

You set the pace for the man behind;

Step faster, please!
