Whenever I do that my band director says "Every time you hit your flute you kill a flute fairy." and eventually I (accidentally!) hit my flute so many times that he just said, "I'm pretty sure the flute fairies are extinct.
Ah, the junior high flutes. Im that one that always has to tell them the note fingerings.except they're flutes and I'm a clarinet. Pretty sad that I know their fingering when's I've never played a flute.
