It started out as any other story other boy meets girl, girl falls madly in love with boy and they marry...how lovely. The boy was a king and had a daughter with his now deceased wife. The girl accepted this and was very hopeful of their relationship together and of hers with the motherless daughter. She planned to love this child with all her heart and fantasied about living happily ever after. 
This however was not to be. It was soon blatantly obvious that the king was not over the death of his first wife, and the girl was only there as a substitute mother to their offspring and a bed warmer for him. The resentment started to grow, people around town rumoured she had cast a spell on the king to force him to marry her, sadly the opposite was true. Not with magic, with his loving words, his kind actions and his lies. 
The child never shut up constantly singing her monotonous song, she believed she could speak to animals and would bring vermin in the house on a regular basis, she would sit by the roses and sulk for hours, she never did any chores or schoolwork and pranced around every waking moment singing like a deranged lunatic. Everyone else thought Snow White was charming, the queen however knew better.
Her father died and now the step mother was responsible for this little twit. She tried to get her to do the chores and schoolwork, she tried to connect with her in shared grief but there was nothing she could say or do to mend the relationship after so long.  
The final straw was when Snow White ran away from home stealing her stepmothers "fairest of them all" trophy to pawn and moving in with seven men. The queen went to visit once in disguise and was so disgusted by what she saw she never went to see her step daughter again.
