Love and Need

The kid and I were discussing how much she loves drawing, how much I love writing and teaching.

I found Frost's Two Tramps In Mudtime for her.

Nothing on either side was said. 
They knew they had but to stay their stay 
And all their logic would fill my head: 
As that I had no right to play 
With what was another man's work for gain. 
My right might be love but theirs was need. 
And where the two exist in twain 
Theirs was the better right--agreed.

But yield who will to their separation, 
My object in living is to unite 
My avocation and my vocation 
As my two eyes make one in sight. 
Only where love and need are one, 
And the work is play for mortal stakes, 
Is the deed ever really done 
For Heaven and the future's sakes.
