I've Grown Accustomed to His Face [From My Fair Lady]

I've grown accustomed to her face
She almost makes the day begin
I've grown accustomed to the tune
She whistles night an' noon

Her smiles, her frowns
Her ups, her downs
Are second nature to me now
Like breathing out and breathing in

I was serenely independent
And content, before we met
Surely I could always be that way again, and yet
I've grown accustomed to her looks
Accustomed to her voice
Accustomed to her face!
