Daily Warm Up: The Speaker of a Poem

Me:
Today, I fought with my Sister
She said that she wanted a new Mister
I told her that she was already betrothed 
and that she would lose her humble abode
She has two children and a cat
They would miss her and that was that
She made up her mind to stay
i said "good" and that's all i could say

Sister:
Today, i fought with my sister
because I've met a new mister
She said that i was married
and that i had to be wary
My children and cat
would frown at that
i decided to stay at home
and regain my beloved throne.
