The right eye I avoid blinkin',
There is a new irritant therein,
But harmless compared to the killer,
The killer roamin' here an' there,
Thousands of faces she always had,
And she dons one or the other,
Kills by the name of the lover.

Irritant

Ever since you started following me I realised you are a husk of a soul.

Your mere presence is irritating. 

The fact that you're being an irritation bolsters my assessment that you are actually an irritating being. 

What's it like to be an irritant? 

Not sure. 

I know you're being a stimulant.
