A        Amaj7
I lived in a house
          D            Bm
My height on the walls
                  A     Amaj7
right next to my sister's
           D            Bm
who lived down the hall
                   A     Amaj7
at night we would knock
                  D        Bm
on the wall that we shared
          A        Amaj7
sleep head to head
              D     Bm
I miss being there

[Chorus]
A Amaj7 D
Ohh oh oh
         Bm
this is what I used to know
A Amaj7 D
Ohh oh oh oh oh
         Bm
this is what I used to know

[Verse 2]
A          Amaj7
My piano teacher
D               Bm
She lived next door
A             Amaj7
We tried and failed to make
D                       Bm
her fudge when she got sick
A              Amaj7
I quit taking lessons
             D     Bm
cause I got bored
A                  Amaj7
I used to like her son but
           D           Bm
he turned out to be a dick

[Chorus]
A Amaj7 D
Ohh oh oh
         Bm
this is what I used to know
A Amaj7 D
Ohh oh oh oh oh
         Bm
this is what I used to know
F#m A Amaj7
ohhhhhhhhhh

[Bridge]
F#m         A
snuck out once
              Amaj7
but it wasn't worth the worry
      F#m           A
went down the street
          F#m
to meet a boy who wasn't
D                E  E#  G
good enough for me

[Verse 3]
A            Amaj7
My dad had a mustache
D               Bm
that he let me shave
A                   Amaj7
He thought he could help us
D             Bm
He wanted to save us
A          Amaj7
from each other
       D          Bm
cause we had gone mad
A             Amaj7
Forgotten the good things
D              Bm
forgot what we had
 
[Chorus] 
A Amaj7 D
Ohh oh oh
         Bm
this is what I used to know
A Amaj7 D
Ohh oh oh oh oh
         Bm
this is what I used to know
                             A
this is what I used to know
