  Have you guys ever used ear buds? Those things that we use to clan the ears (they have cotton swabs at either end..ring a bell?) well I have often had this difficulty which is that when I use them for some reason the cotton starts to unwind.... and so I have to rotate it in the opposite direction. Now if the company that is manufacturing it were to print on the plastic stick the direction of the motion in which the swab has to be rotated to clean the ear it would make my life easier....
