Hi Sasha, one of your recent posts were how you have been irritable since his death. Kid will have moments of irritability also. She's lost her father's source of teaching her to drive. It probably comes across as not fair. When I lost my mother I took the not fair out on strangers.
Learning to drive seems to be a big event for her. Letting her voice that frustration even if it doesn't make since to you will help your daughter grieve. Is there another family member or friend that could help her drive? I had an uncle who was a driver's instructor when my parents wouldn't/couldn't teach me.
