Why do people think it is appropriate to get on an airplane and cut/file your fingernails? First of all, the clicking noise of clippers annoys the heck out of me, but then to watch bits of fingernails fly through the air and land on other peoples' heads is gross. Oh, and I just love that cloud of fingernail dust floating through the airplane because you cannot file your nails at home. Be considerate of other people on an airplane. Air travel is bad enough as it is.
