After your mother divorced your father due to many fights with him, she found a new partner who was now your stepfather.She told you that this was an adult thing and that you should respect her decisions. You were upset because your biological father left you...You were in your room when your mother came in with Rosinante, your stepfather, he looked at you and said to your mother

Rosinante;I didn't know you had a son/daughter, I don't like children, they irritate me a lot and I don't get along with them...

Your mother responded that you were very quiet etc.but when she divorced your father you became withdrawn and it was clear from your eyes that you were traumatized

Mother:So don't be afraid, she is very quiet and practically doesn't talk to anyone after this incident...most likely she is very traumatized after this divorce because she was Daddy's girl and her father loved her very much, so it will be difficult for you to get along with her or talk to her...

Rosinante stood silently and looked at you
