I recently had a coworker that had a medical issue that required him to have someone around. Typically a spouse, adult child, roommate, friend, etc. could fill that role, but when the medical staff asked him who he had, he realized that he had no one and didn't have an answer to their question. He ended up having to pay a nurse type person to come and stay at his house with him. I prefer solitude myself also, but after hearing about his experience I'm glad that I have some people in my life I can rely on.
