Analysis of Billy's Policeman

I knew a policeman once
And this is true as it ever could be
Who made me feel an awful dunce;
'Cos I lost my dad, and it frightened me.
He came and took me by the hand
'Well, now,' said he; 'young fella-me-lad,
No need to cry, I understand.
You'll soon be back with mummy and dad.'

I knew the big policeman well
Before he'd talked the teeniest while.
Such a lot of things he had to tell;
And he had the cheeriest, merriest smile.
I've got a nipper at home like you
So high, young fella-me-lad,' he said.
And all at once - as true as true
I forgot to cry, and I laughed instead.

And then the big policeman said:
'Ho, that's the stuff for the troops, old son!'
The funniest things came into his head;
And I laughed and laughed at every one.
And when they found my mummy and dad,
And he patted my head and said good-bye.
Somehow or other I felt quite sad;
But I knew he'd be sorry to see me cry.

I know that all policemen now
Are just like that, and it's silly to think
They frown and bully and make a row,
Why, you ought to have seen my merry one wink!
And when I pass where he has his beat,
When I'm out for a walk with mummy and dad,
I wave to my big friend in the street,
'What Ho,' says he, 'young fella-me-lad.'
