Six Serving Men (by Rudyard Kipling)

I Keep six honest serving-men:

(They taught me all I knew)

Their names are What and Where and When

And How and Why 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.

I let them rest from nine till five.

For I am busy then,

As well as breakfast, lunch, and tea,

For they are hungry men:

But different folk have different views:

I know a person small -  

She keeps ten million serving-men,

Who get no rest at all!

She sends them abroad on her own affairs,

From the second she opens her eyes -

One million Hows, two million Wheres,

And seven million Whys!
