A gift from Nicholas Kurti

I find again what Nicholas offered me when I was 40 yo :


I keep six honest serving-men
(they taught me all I knew);
Their names are What and Why and When
And How and Where and Who.
I send them over land and sea,
I send them east and west ;
But after they have worked for me,
I give them all a rest.
(R. Kipling)
