liese, you have my sympathies. I remember long, long ago, getting a little paint on a classroom rug during a project and being asked to work more neatly. I was young and passionate and had not learned how to bite my tongue, yet. I am very careful about pencils. We had one custodian whose rule was if it was on the floor, it would be swept up. The one we have now is great. He's even rescued lost earrings.
