Choice/No choice

I wanted to show my friend her ability to choose in her life. I used the example Brooke uses saying we choose to pick up our kids from school, we could leave them there if we want. I understand that concept, but she just can’t see it at all. She only sees the responsibility of having kids and there’s no possible way we could leave them there – there’s no choice – she HAS to pick them up. Any advice on how can I flesh that out with her?
