In voices

I read the last post and got confused for a second because I thought I said writing in voices, which wouldn't make sense because voices are just sound produced by continuous and regular vibrations made by another human being's vocal chords, which to my knowledge isn't like an invoice at all. I got a real laugh when I realized my mistake, but then I remembered a post I once wrote about gum disease, which is no laughing matter, and that shut me right up real quick.
