I was thinking third limited, actually. Alex goes to the grocery store, she picks up bananas, ze picks up crackers, she thinks things about rising prices that are inappropriate to say in front of the little kid sitting in the cart two feet over, ze picks up milk, she pays the cashier, ze goes home. Except more in-story time passes between each change. I have no idea how I could do this without using third-person pronouns to distinguish genders.
