Written for a child (possibly one of her young sons) ‘tricky’ is a mother’s desire for her son’s well-being and good behaviour

I’ll tell you of a friend of mine

He’s got a little house

He does a lot of work for me

He’s smaller than a mouse.

I wonder if you’ll have a guess

at who this friend might be?

He’s not a boy or girl I know

but he’s a part of me!
