That is a hard question to answer. I'm inclined to say my family, but that's obviously more than one person. Molly is probably close to the top of the list, but I'm not sure I can say I care more about her as much as worry most about her. I would say William, but then I feel like I'm shitting on my family, who I care about a lot.

To escape all of that, perhaps I'll just say my dog.
