A backpack would be better, but I don't have any. I keep the zippered nylon bag inside my nylon briefcase in case something happens at the office, such as a firedrill.<br><br>I also use that case when I'm trying to be inobtrusive. If we go out for a fancy dinner, I can't bring my normal shoulder bag, because I don't want people staring (rude buggers), so I bring that smaller one.
