I've always got my ipod and phone on me. During winter, I've got my slippers in the house. When I'm not in the house, I've got a huge jacket that has a hood that weighs more than my head (overstatement, but it's a real heavy hood).
When I go to school, I have my iPod w/headphones, mechanical pencil w/extra led (0.5 mm), my student ID, and my usb drive. Oh, and my books, binders, and notebooks.
Question to all those who have replied: Those of you who carry a pocket knife around... why?
Carrying around a blade of any kind is illegal in Australia and punishable with a $1000 on-the-spot fine, which actually causes problems for tradesmen who wear their toolbelts as a matter of habit for example. The rationale is that people are more likely to use anything at their disposal as a weapon, and since guns are not accessible to the majority of the Australian public, we've been seeing a spate of stabbings and slashings lately.
