Companion Care Needed

About who needs care: My father has Stage 5 dementia and a TBI. At this point he sleeps a lot. We basically need someone to just be in the house while my mother runs errands because he can't be left alone. About the care needs: My mother is not really interested in having the care giver do much right now, in terms of bathing, exercise, house tasks, etc. He has dementia and we need someone who won't get easily offended. I think anyone who is experienced with dementia patients would understand. His native language is Spanish, he likes movies, books, and he can still play dominoes. Services needed include: companionship.
