DEAR ABBY: I have a question about nail-biting/finger chewing. We recently hired a new employee who is in daily contact with the public. He is a finger chewer, and his nails are bitten well below the finger tip. I am struggling with this because I had a childhood friend who chewed her fingers to the point of bleeding, and I have a strong negative reaction when I see people do it.
When, if ever, is it appropriate to speak to someone about this bad habit? I have recently learned that it is actually a medical diagnosis and can lead to gastric disorders. We all know there are many germs on our hands, and every time you put them in your mouth, you're transferring them to your intestinal tract. -- WORRIED IN THE EAST
DEAR WORRIED: I have heard of very few nail-biters who are proud of the habit. There's a saying -- not original -- that if you want someone to avoid you, just tell him something "for his own good." If you want a pleasant working relationship with this person, mind your own business and do not attempt to "help" him by offering unasked-for advice.
