Companion For Smart, Stubborn, Man, With Short Term Memory Loss

I'm looking for a man - he respects them more - and he has balance issues - the man lives at home in manhattan - this would be a daytime job-- the man must be kind, yet assertive, and have a sense of humor-- and my stepfather must like him-- the care provider would accompany my stepfather when he wants to leave the house - he worships his independence but he has fallen before so this is tricky... if you are interested - let's communicate - thank you
