Tuft of Flowers by Frost...

...And feel a spirit kindred to my own;
So that henceforth I worked no more alone;

But glad with him, I worked as with his aid,
And weary, sought at noon with him the shade;

And dreaming, as it were, held brotherly speech
With one whose thought I had not hoped to reach.

‘Men work together,’ I told him from the heart,
‘Whether they work together or apart.’
