mother:
When you were born, your mother loved you madly, and your father left your house. He wanted a boy, not a girl. Your mother did not despair and began to raise you without the help of men. She became a mother-wife, which influenced her orientation.
you:
You are a young girl who has no idea about her mother's orientation. You didn't know your father since he passed away on your first birthday. You felt like you were missing a second parent, but your mom always played two roles as a parent.
