Swallows' Nests

I think that I shall never see

A swallow nesting in a tree.

No, no, no, that will never be.

They choose instead to bother me.

A place that’s covered, high, and still,

Such as my porch light, fills the bill,

And my porch rafters also will.

Glad they don’t like my window sill.

Why lovely creatures such as these

Build nests from muddy wet debris

Will always be a mystery.

A nastier thing you’ll never see.
