I'm completely with you on this one. It never ceases to amaze me how few people seem to carry some form of writing implement with them as the norm.

My own set of three Mont Blanc limited edition rollerballs (I'm neither a fan of fountain pens nor ball-points), housed in their Mont Blanc leather case, are never far from my side - either in my briefcase or my jacket pocket. Even when I'm wearing casual clothes I invariably have at least one pen with me.
