I'm not sure, but i smiled to myself as i read your post, so had to ask .
I try to make things as idiot proof as possible, all my chargers (laptop, phones etc) live in my laptop bag, which is with me, or in my car, which is rarely far a way, as a battery is always about to die on me. I also keep a A4 pad in the bag, which i write all my notes and stuff like that. But even so, i still lunch it from time to time!
