A word is a sparrow

"A word is a sparrow", she said; 

Perhaps I should have listened,

And maybe you would have stayed instead,

But I saw the tears that glistened.

All those lives that I have destroyed,

Of whom I love so dearly,

But all of whom are now annoyed;

I ruined their lives severely.

I'm so sorry, I really am, 

I was selfish and greedy. 

Though you don't think it's worth a damn,

I'm so sorry for being seedy.
