Digging in your nose in public like you’ve got diamonds in your head is DISGUSTING!!! Use a tissue! Or here’s an idea – keep your finger out of your nose until you are alone! An old woman on the bus was digging (not picking, but digging) in her nose continuously. She took out a tissue to blow her nose and then continued her digging WITHOUT THE TISSUE! To top it off, she then pushed the “descendre” button with her booger-digging hand. I was already a germaphobe about public transportation, now I’m a booger-phobe too.
