Not exactly so.

What's one thing that you never go anywhere without? I don't mean your wallet, ID, or those essentials that you should be carrying (you can include them if you feel it is important to), but something not necessarily needed, like a favorite watch, belt, or hat. It could be a teddy bear; heck, I don't know what people drag around these days.

But share.

As for myself, I always carry at least one ball-point pen around. Very boring, I know.
