Verse [Arpeggiated]
Em                   C
Beating the drum all night
G
Dancing naked around a fire
Em              C
Leaving trouble behind
G
Swimming in the water
            Em             C
We found the tent with the flashlight
        G
We were looking for a hideout
            Em             C
When you’re praying for no strings
    G
Sometimes you get tied down


Chorus {Arpeggiated]
Em    C                             G
And I never thought that this would happen
Em      C                       G
And you got all weird after the weekend
Em        C                    G
Sometimes you make out with an old friend
Em      C                      G
And I’m rounding first and I’m sliding into second

Verse [Arpeggiated]
Em                       C
She could never hold her tongue much
G
And when I bit her lip hard
Em             C       
Expecting some review like
G
2 out of 5 stars
       Em                    C
But in a moment she revealed that
G
She was no different
            Em             C
We were just kid’s nervous breathing
G
Showing some forgiveness

Chorus [Chords Strummed]
Em    C                             G
And I never thought that this would happen
Em      C                       G
And you got all weird after the weekend
Em        C                    G
Sometimes you make out with an old friend
Em      C                      G
And I’m rounding first and I’m sliding into second

Post-Chorus [Chords Strummed Once]
Em
And if you don’t know
C
Then I don’t know
G
How these things go
G
Ooh ooh ooh ooh ooh ooh

Verse [Palm-muted]
Em                      C
In your wooly socks and Birkenstocks
G
What would they say about us
Em                 C
At the hour of the evening
G
The night will carry on without us
Em                    C
But if we had to play one card
G
And say we both blacked out
Em                      C
And my friends seems to trust us
G
They believe this silly kinda of cop out
Let me tell you now

Chorus [Chords Strummed]
Em    C                             G
And I never thought that this would happen
Em      C                       G
And you got all weird after the weekend
Em        C                    G
Sometimes you make out with an old friend
Em      C                      G
And I’m rounding first and I’m sliding into second

Post-Chorus [Chords Strummed Once]
Em
And if you don’t know
C
Then I don’t know
G
How these things go
G
Ooh ooh ooh ooh ooh ooh
