Am                                      C                         Dm
Same bed, but it feels just a little bit bigger now
G                 G7                         C                                 Em/B
Our song on the radio, but it don\’t sound the same
Am                                                 C                                 Dm
When our friends talk about you all it does is just tear me down

Cause my heart breaks a little when I hear your name

It all just sounds like ooh, ooh, oooh, oooh
Bb                                                 C/G
Mmm too young, too dumb to realize

[Chorus]
G                                 F                 G                                 C
That I should\’ve bought you flowers and held your hand
F                                                 G                                 C

F                                                                 G                                 Am
Take you to every party cause all you wanted to do was dance
D7                 F                 Fm         C              F         C                 Em/B
Now my baby\’s dancing, but she\’s dancing with another man

[Verse 2]
Am                                 C                                 Dm
My pride, my ego, my needs and my selfish ways
G                                 G7                                 C                 Em/B
Caused a good strong woman like you to walk out my life
Am                                                 C                                 Dm
Now I\’ll never, never get to clean up the mess I made ooh
G                                                                 C
And that haunts me every time I close my eyes

[Refrain]
Em/B                 Am                                 Em
It all just sounds like ooh, ooh, oooh, oooh

Mmm too young, too dumb to realize

[Chorus]
G                                 F                                 G                                 C

Shoulda gave you all my hours when I had the chance
F                                                 G                                 Am
Take you to every party cause all you wanted to do was dance
D7                                 F                                 Fm                                 C
Now my baby\’s dancing, but she\’s dancing with another man

[Bridge]
F       G                  C                 G/B                 Am                 Em/G
Although it hurts I\’ll be the first to say that I was wrong
D7
Oh, I know I\’m probably much too late
Dm
To try and apologize for my mistakes
G
But I just want you to know

[Chorus]
F                                                 G                                 C
I hope he buys you flowers, I hope he holds your hand
F                                 G                                 C
Give you all his hours when he has the chance
F                                                 G                                 Am
Take you to every party cause I remember how much you love to dance
D7                                 F                               Fm                 C
Do all the things I should\’ve done when I was your man
D7                                 F                                 Fm                 C
Do all the things I should\’ve done when I was your man
