your school is across the street from your moms office so you ride with her to work then walk across the street. what kind of relationship does this describe

A woman worked for us during the last two months of my mother's illness. She must have found us appalling. A week or so before my mother died, my brother and I started packing up the apartment right in front of her. I know this sounds grotesque, but we were haemorrhaging money and had to do whatever we could to stem the flow.

If you are referring to symbiotic relationships then it is either mutualism or commensalism because (respectively) you could both benefit because you get a ride and your mom needs not worry or you get a ride and your mom is not affected.
