We look at life through the space we locate ourselves in.
When you go home for the holidays, you have a space inside which you interact with your mother. You have a space inside which you interact with your father, another space with your siblings.
Some people live their whole life out of one favorite space.
When you know what space you think you are in, and the other person makes no sense, that is because they relate to you inside a different space.
For example, Nancy lives inside Mother-child space. She is either the mother, or she is the child. When she is the child, I am either the mother (she loves that) or Not mother… she hates that.
This is invisible for her. It’s the water she swims in.
