Contextual Analysis of "full grown" in Lyrics

it's so hard to leave their table

and my i've grown some very big teeth

i'm not your possession

here's the thing you wanna put me in fancy clothes

is nothing i'm told

you can test my dna but. that's what i'm made of

but when i get her all alone

she's full grown

the holly and the ivy

of all the trees that are in the wood

the holly and the ivy

of all the trees in the wood

but when i get her all alone

she's full grown
