Verse 1
Emaj7
I know girl, when you look at me
C#m
You don't know how I feel
Emaj7
Cause I'm usually so nonchalant
C#m
My feelings I conceal
                  F#m
But I want you to know
                    B
Oh, I want you to know
Emaj7                                 C#m
I must admit I've felt this way for more than quite a while
Emaj7                                 C#m
But I can't hold it no longer when I see that pretty smile
               F#m
Can't wait no more
                    B - C
Oh, I can't wait no more

Oooh

[Chorus]
Emaj7                  C#m
Girl, to tell you the truth
                 F#m
It's always been you
               B
I'm all about you
    Emaj7
Oh, girl
          C#m               F#m
No one can do me the way you do
                 B
It's always been you
I'm all about you

Verse 2 (Chords same as Verse 1)

Emaj7                         C#m
Maybe I'm a fool for speaking up but I don't mind
Emaj7         
Cause a girl like you will come around like
C#m
Once in a million times
             F#m
So what do I do?
                 B
Tell me what do I do
Emaj7                                   C#m
And the look that you are givin' me gives me hope to believe
Emaj7
So for you baby I'll change my ways I'll
C#m
Wear my heart on my sleeve
               F#m
Got nothin' to lose
                   B - C
I've got nothin' to lose


Repeat Chorus


Bridge:
              Abm
Girl when you smile
                      C#m
Not a place I'd rather be
                 Abm
Just stay for a while
                           C#m
Then you'll see you should be right here with me
             F#m
Cause I love everything you do
             Emaj7   Emaj7(slide barre finger down 1 fret)
That's why I have to take 
     C#m   B         F#m
this time baby to tell ya
                B
Oh, and now you know
            
And now you know
