My MIL! She was a dear, sweet, kind woman with one really bad habit. We ended up in the restaurant restroom at the same time and she headed straight for the door. When I asked her if she was going to wash her hands, she replied, "That's just for dirty people." I wanted to tell her, "If you don't wash your hands after using the bathroom, you ARE the dirty people," but didn't. Back at the table, I could no longer eat from the family-sized basket of fries I'd bought ... because she was using her fingers to pluck them out as she ate. EEEEeeewww!
