She Was Lucky I Was There<br>I was in the noodle aisle at the grocery store a couple of weeks ago. A woman ahead of me was pushing a cart with a child in its seat. She'd given the small boy her purse to occupy his attention. As she was looking at food, the boy threw her wallet on the floor. I tapped her shoulder and let her know that he had done that.
The woman was pushing a cart with her child in its seat. 
The text says she was pushing a cart with A child in its seat. It is never specified whether she is parent of the child. The model just assumed it.
