Humming

mmmmmmmmmmm

very glad the dedicated humming account agrees that it's *almost* perfect—for instance, as a oral habit, when done in the wrong part of your mouth with the wrong mouthfeel, you have a kazoo, not a tone, and it creates an uncomfortable tickle. or, winged animals can flap against your ear, and the brief friction where the humming sharply changes is deeply uncomfortable. it's very nice regardless.
