Apathy.
Noun: 1. Lack of interest or concern, especially regarding matters of general importance or appeal; indifference. 2. Lack of emotion or feeling; impassiveness. (Thank you American Heritage Dictionary fourth edition)
Ex. Apathy can allow a person to get through the day merely by repeating this simple mantra: I don’t care. I don’t care. I. Don’t. Care.
Sigh. I think now might be a good time to break out Battlefront II. There are some silly rebels who need to be obliterated tonight.
