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.
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.
