anything used for personal grooming (toothbrush, makeup, makeup brushes, hairbrushes etc)
In the office: my mug. I drink tea and i like my china mug. Do. Not. Touch.
Anything that has personal settings (car, office chair etc) because they never set them back properly (ex-boss had THE BEST CAR EVER it saved your settings - seat position, mirrors, even the temperature if you wanted - and i was so jealous of that)
I can hear you thinking that my fabric scissors would be great for cutting your paper. I can hear that thought before you can. Start running.
