Should've Said No -- Taylor Swift

It's strange to think the songs we used to sing
The smiles, the flowers, everything is gone
Yesterday I found out about you
Even now just looking at you feels wrong
You say that you'd take it all back, given one chance
It was a moment of weakness and you said yes
You should've said no
You should've gone home
You should've thought twice before you let it all go
You should've known that word
'Bout what you did with her
Get back to me
And I should've been there
In the back of your mind
I shouldn't be asking myself why
You shouldn't be begging for forgiveness at my feet
You should've said no
Baby, and you might still have me
You can see that I've been crying
And baby you know all the right things to say
But do you honestly expect me to believe
We could ever be the same
You say that the past is the past
You need one chance
It was a moment of weakness and you said yes
You should've said no
You should've gone home
You should've thought twice before you let it all go
You should've known that word
'Bout what you did with her
Get back to me
And I should've been there
In the back of your mind
I shouldn't be asking myself why
You shouldn't be begging for forgiveness at my feet
You should've said no
Baby, and you might still have me
Ohhhh
I can't resist
Before you go
Tell me this
Was it worth it
Was she worth this
No, no no no
You should've said no
You should've gone home
You should've thought twice before you let it all go
You should've known that word
'Bout what you did with her
Get back to me
And I should've been there
In the back of your mind
I shouldn't be asking myself why
You shouldn't be begging for forgiveness at my feet
You should've said no
Baby, and you might still have me
