I Can't Breathe Without You

Besides money or another person, what's the one thing that you ALWAYS have to have with you everyday? Something that makes your day all wrong if you forget it/don't have it...makes you feel nekkit. Something that if you ran into someone from the forums, you'd have it with you if they asked? Something that your folk can say, "You'll never catch her/him without _____!" Your camera? Headscarf? Fitted cap? Polo shirt? Latest handbag? Jewelry? The Latest Js/shoes? Hair did? etc... What's your one thing/trademark?
