I have one this year and it just grosses me out to no end. I've verbally chastised the girl and told her how nasty it was for her to put her dirty thumb in her mouth and how she spreads germs everywhere she touches afterward. I get the sheebie weebies just thinking about grading her papers. And, I have a touch of germaphobia to start with! Knowing the H1N1 is going around doesn't help either. I can deal with a lot of issues but this is just one makes my skin crawl. Anyone have any suggestions?
