I shouldn't sing. I attended Catholic Grammar School and the nuns would encourage students to sing. "Singing is like praying 7x", they'd say, "Except Reiser, you should lip-sync". I do sing in Church, I figured if God gave me this voice, I might as well make Him listen to it.
If I knew my bible then I would've pointed out that Psalm 98 says I should make a "Joyful Noise unto the Lord" and my singing is noise.
