My Name

My name is proficient, businesslike.
It has the ability to be punctual.
It requires little effort.
Yet when sighed in pleasure, or called in happiness,
My ears gloss over the familiar corners of my identity
And turn my name into a new conglomeration
Composed of unfamiliar vowels and consonants.
I cannot hear my name spoken in joy.
It sounds foreign, a strange sound of exaltation.
That surely cannot be my name.
You cannot be referring to me.
That would mean that my name has other capabilities
Beyond my standard identifiers.
Who is this person you speak of?
