I'm in a mucky internal reflection phase*, and this thought keeps popping into my head like an involuntary mantra: "Just because I know the words doesn't mean I have to sing the song."

Once it was even literal, so there you go.

* I expect to shake the phase any minute...now. No, wait...now! Nnnnnnnnnnnnnn...now! Dammit! Stupid introspection. Don't make me kill you with television, because I swear, I'll do it.
