I've Grown Accustomed to Her 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 and 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 look
Accustomed to her voice, accustomed to her face

I'm very grateful she's a woman and so easy to forget
Rather like a habit one can always break and yet
I've grown accustomed to the trace of something in the air
Accustomed to her face
