A leech is a useful insect,

And good for medical treatment at that,

A mosquito is not,

And a pest at that.

A cat is expensive when it is Siamese,

And pampered at that,

A stray is worthless,

And dirty at that.

A diamond is picked out of so many,

Which are also diamonds similarly,

But because they are the wrong shape and size,

Are thrown away like dirt.

Many ask why,

Many cry foul,

They themselves do not know,                                                                              

They are the cause.

To be worthy or worthless,

Is but a slight difference,

A fine line,

Dealinated.
