"I should only believe in a God that would know how to dance. And when I saw my devil, I found him serious, thorough, profound, solemn: he was the spirit of gravity- through him all things fall. Not by wrath, but by laughter, do we slay. Come, let us slay the spirit of gravity!" - Nietzsche

I sing too often in home. When I had a roommate the situation was that I sang too much for my own good. One of my roommates ended up adopting a passive aggressive attitude by turning on music loud whenever I was home. I had to eventually stop singing. I also often sing in the streets and many a times I see a young attractive man who catches my fancy I cant help singing. No doubt they stay away because I am a horrible singer and I bet it must be a huge turnoff.
I sang of leaves, of leaves of gold, and leaves of gold there grew.
