POEM by Matt: Guess Who?

I am an artist
Whose talent has no predetermined value
I need not for I am wealthy in every way
There are others like me, though hard to find
I am with you always you, noticing your every flaw
I dream with you
I share your day
You cry, I cry
I have the power to cheer you up
Though not in my job description
I'm here to protect you
If you knew the instrument I mastered
You'd have figured me out
They nicknamed me "guardian"
I probably was fed Red Bull since birth
And the instrument mastered
Is the harp
I'm here for you always 

By Matt.
