When I'm feeling down I like to whistle. Real loud and real quite too. So quite I can't hear myself and so loud everybody can hear me. If you hear me whistling you will know I'm depressed and upset. Don't try to cheer me up it won't work. When I'm whistling the outside world doesn't appeal to me I'm to involved in whistling to care. I can get so absorbed in whistling its like the whistle is absorbed through parts of my body and I start to move along with the tune. A lot of times I find my self dancing while I whistle. If you like to dance come by while I'm whistling I'll blow you a tune you can dance too. If you think you whistle good I'll out whistle ya. Positive of it.
