You slap him.
He didn't slap back.
In fact, he stated he doesn't hit women.

But his sister will.

You hit him,
He walked away.
Made a phone call and requested that you wait.
Which you did.

Soon, at the door.
Which he open.
Was his sister.
And she fights women.

Especially, if she hit her brother.
Call it sister love.
For what he won't do?

His sister will.
