Random door knocking

I know a girl
When you stumble...don't get up
But you shave
When you pretend to be strong...
turns into a tree,
And when you ignore
It was as if she had suffered memory loss
Very precise and decisive
I know a girl
Nails are hammered
With one look in her eyes
And the dull doors are closed
With her stubborn hairband,
She is good at cooking pasta, pizza, and other things like men.
