I do most but not all of those. 1, 2, 3, 5, 6, especially 7, 8, 11, 13, 16, 18, 20, 21, definitely 23, 24 - though that's more of a weird compulsion rather than fear of somebody behind the curtain, 25, 27 (though I'm more irritated than nervous. I pay you to cut my hair, not start a conversation, so shut the fuck up.), 28, 30, 31, 32, 33, 34, and 36.
