Once, during an interview in front of my wife, I was asked, "Are you one of those actors who brings your character home? Do you stay in character?" I said, "No, not really. I don't do that," and she started laughing. I asked her why. She said, "Well, you might think you don't bring characters home, but you do." So, while I don't feel like a character is lingering, it probably is.
