"Undo it" - Carrie Underwood

Lyrics:
I should have known by the way you passed me by
There was something in your eyes and it wasn't right
I should have walked but I never had the chance
Everything got out of hand and I let it slide

Now I only have myself to blame for falling for your stupid games
I wish my life could be the way it was before I saw your face

You stole my happy, you made me cry
Took the lonely and took me for a ride
And I wanna uh-uh-uh-uh-uh-undo it
You had my heart, now I want it back
I'm starting to see everything you lack
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

Na, na, na, na, na
Na, na, na, na, na
Na, na, na, na, na, na

Now your photos don't have a picture frame
And I never say your name and I never will
And all your things, well I threw them in the trash
And I'm not even sad

Now you only have yourself to blame for playing all those stupid games
You're always gonna be the same and, oh no, you'll never change

You stole my happy, you made me cry
Took the lonely and took me for a ride
And I wanna uh-uh-uh-uh-uh-undo it
You had my heart, now I want it back
I'm starting to see everything you lack
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

Na, na, na, na, na
Na, na, na, na, na
Na, na, na, na, na, na

You want my future, you can't have it
I'm still trying to erase you from my past
I need you gone so fast

You stole my happy, you made me cry
Took the lonely and took me for a ride
And I wanna uh-uh-uh-uh-uh-undo it
You had my heart, now I want it back
I'm starting to see everything you lack
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

You stole my happy, you made me cry
Took the lonely and took me for a ride
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

General Idea/Story Inferences: 
I think this song is about a girl who see's this guy, and the moment she see's him, she knows he's trouble, but they get together anyways and problems just occur.  After they have been together for a while, she starts to figure out who he really is and how he acts.  She doesn't like what he starts to become, and then wishes she could undo everything that ever happened.  She wishes she never saw him in the first place.

Quote Inferences:
1. "There was something in your eyes and it wasn't right" - From the very first time she ever saw him, she could tell something was different, like he wasn't a guy you would want to mess around with.  She knew it wasn't really something good, but she went for him anyway. 


2. "Everything got out of hand and I let it slide" - There were a lot of problems and arguments about things, but she never really felt like it was something she needed to deal with.  It started to get worse, and she still did nothing. 

3. "I wish my life could be the way it was before I saw your face" - She just wishes that she had never even seen his face in the first place, because she could have had a better life without him.  Now she's living life with regret, and doesn't want him there anymore.

4. "Took the lonely and took me for a ride" - She was hanging out all by herself, and he decided that he might as well just pick her up and take her for a ride. She ended up having the time of her life, while he really didn't even care.

5. "Now your photos don't have a picture frame" - The pictures that she has of him and her, don't have frames around them anymore. Because he's not really a big part of her life anymore. He's not important to her.
