Irene was more than a companions or caregiver to Mom. Her dedication to Mom’s comfort and well-being equaled or exceeded that which might be expected from a close relative. The care Irene provided Mom certainly was a lot more comprehensive and professional than the care any close relative might be able to provide in a similar situation. Irene added purpose to Mom’s life, which, to my way of thinking, probably extended Mom’s life by a little, allowing family members to spend precious time with Mom.
As our parents or grandparents age, we might find that a change in their living situation is necessary. The most likely scenario is if mom falls and breaks her hip. This unfortunately is very common.
