            EmI'm (022000@1)saying hush little baby
Don't you cry
CDaddy (x32010@1)ain't sure he can raise you right
GI (320003@1)ain't even good with saving my money
Why should I think I could save your life
EmThe (022000@1)whole family's gonna think I'm a devil
CCos (x32010@1)I don't want to see my angels eyes
GI (320003@1)say this with one hand on my heart
Guilt ain't gonna make me change my mind
EmMy (022000@1)first thoughts were my worst thoughts
CRunning (x32010@1)through my head in circles
GThe (320003@1)world's gonna hate me for saying this
But patience is a virtue
EmSo (022000@1)we don't have to rush
For our first yute
CWe (x32010@1)could take time do rehearsals
GAnd (320003@1)I ain't acting, this is personal
And I ain't doing this just to hurt you

[Chorus]
Em (022000@1)               C (x32010@1) GI (320003@1)should say goodbye before I say hello
             Em (022000@1)   C (x32010@1)     GSo (320003@1)darling hold me closely tonight
            Em (022000@1)         C (x32010@1)       GCause' (320003@1)if you open your eyes I'll never let you go
        Em (022000@1)          C (x32010@1)        DMoving (xx0232@1)slowly we'll both sleep tonight
              C (x32010@1)               C (x32010@1)DG
And I'll be dreaming till you wake me up

[Wretch 32]
EmWhen (022000@1)I'm telling her about raving
CShe's (x32010@1)telling me about cravings
GI (320003@1)just want her to get the message
I don't want to have to be so blatant
EmSo (022000@1)I told her my life ain't balanced yeah
CSo (x32010@1)the time ain't right
GShe (320003@1)said God's clocks the only one that matters
And it's about time I tried
EmAnd (022000@1)if I listen to my family
CThen (x32010@1)I'll be a new addition to my family
GI (320003@1)can't help feeling peer pressured
Everyone's looking down but
They don't understand me
EmAnd (022000@1)everyone's so suggestive
CI'm (x32010@1)getting mixed messages
But nobody's rang me huh
GI (320003@1)ain't saying this is a game
But when I say the wrong thing
Everybody wants to hang me

[Chorus:]
Em (022000@1)               C (x32010@1) GI (320003@1)should say goodbye before I say hello
