If you want to know who wrote that song, it's called "Shadow" by Ashlee Simpson

"Shadow"

I was six years old
When my parents went away
I was stuck inside a broken life
I couldn't wish away
She was beautiful
She had everything and more
And my escape was hiding out and running for the door

Somebody listen please
It used to be so hard being me
Living in the shadow
Of someone else's dream
Trying to find a hand to hold but every touch felt cold to me
Living in a nightmare
A never-ending sleep
But now that I am wide awake
My chains are finally free
Don't feel sorry for me

All the days collided
One less perfect than the next
I was stuck inside someone else's life and always second best
Oh, I love you now 'cause now I realize
That it's safe outside to come alive in my identity

So if you're listening
There's so much more to me you haven't seen
Living in the shadow
Of someone else's dream
Trying to find a hand to hold but every touch felt cold to me
Living in a nightmare
A never-ending sleep
But now that I am wide awake
Then I can finally see
Don't feel sorry for me-

Mother, sister, father, sister, mother
Everything's cool now
Mother, sister, father, sister, mother
Everything's cool now
Oh, my life is good
I've got more than anyone should
Oh, my life is good
And the past is in the past

I was living in the shadow
Of someone else's dream
Trying to find a hand to hold but every touch felt cold to me
I'm living in a new day
I'm living it for me
And now that I am wide awake
Then I can finally see
So don't feel sorry for me
Don't feel sorry, don't feel sorry for me
Don't feel sorry, don't feel sorry for me

Living in, living in, living in the shadow
Living in, living in, living in a new day

                           if someone said - your love is like smoke it's a metaphor because they are telling you that smoke cannot be caught, so neither can your love.

so what your co-workers daughter has isnt a metaphor as it hasn't got a hidden message. metaphors are similar to similies.. eg. smilie - your eyes are as bright as the moon

                       Metaphor - your eyes are brighter than the moons unseen light.

hope this helps.

Similes are a form of mataphor. He is as strong as an ox. That's a simile. This link may answer all the questions on the topic.

Metaphor

A metaphor is a figure of speech that uses one thing to mean another and makes a comparison between the two. The key words here are “one thing to mean another.” So, when someone says “He’s become a shell of a man,” we know not to take this literally, even though it’s stated directly as if this person had actually lost his internal substance.

Simile

A simile compares two different things in order to create a new meaning. In this case, we are made explicitly aware that a comparison is being made due to the use of “like” or “as” (He’s like a shell of a man). For fun, the next time someone corrects you and says “That’s a simile, not a metaphor,” you can respond by letting them know that a simile is a type of metaphor, just like sarcasm is a type of irony. Resist the urge to be sarcastic in your delivery.

Analogy

An analogy is comparable to metaphor and simile in that it shows how two different things are similar, but it’s a bit more complex. Rather than a figure of speech, an analogy is more of a logical argument. The presenter of an analogy will often demonstrate how two things are alike by pointing out shared characteristics, with the goal of showing that if two things are similar in some ways, they are similar in other ways as well.

Why metaphor?

There are circumstances where either a simile or analogy is the more appropriate vehicle for getting your point across. But coming up with a great metaphor may be your best bet in many situations.

A metaphor carries so much more power than a simile, because it’s direct. Using “like” or “as” to make an open comparison will often diminish the vivid visual you’re trying to paint in the reader’s mind. Likewise, a spot-on metaphor will spark instant understanding for a reader, without the elaboration that an analogy requires.

From here we’ll examine specific ways to use metaphor in your blog posts. Headlines, openings, themes, calls to action and more can all benefit from the use of metaphor, as long as the metaphors don’t suck. We’ll look at ways to avoid that, too.
