Is there anything you prefer not to do alone?
As always, "Everything" and "nothing" are perfectly cromulent answers.
There isn't much I mind doing on my own, and many things I prefer to do on my own, but one of the things I prefer not to do alone is eat. Obviously, since I work at home, I eat on my own at least once virtually every day of my life, so it's not something I'm incapable of doing. But I like eating with someone better, just because I love good conversation while sharing a meal.
That said, if the choice is between eating alone and company who makes me feel like shit about my food choices, I will take eating alone every single time.
