Hello. I'm sure this isn't important to many of you, but it's urgent, and I do need help. I'm getting a tattoo next week, and the tattoo is lyrics from a song. Normally, I'm fine with punctuation, but I can't be too sure when it comes to something that I'll have on my body forever. The lyrics are as follows: "I'm a mixture of water and bone Not a clone or a stepping stone." Is there supposed to be a comma after 'not'? I feel like it goes there, but again, I need to be sure. Thank you!
