I’ve never actually heard or seen someone honor such a request online or IRL, and it would sound ridiculously stilted if they did. Where is Rumpelstiltskin’s coat? Rumpelstiltskin must have left it at the bar. Will someone please text Rumpelstiltskin and let Rumpelstiltskin know?
It is. You use it if you don’t know a person’s sex or preferred pronouns.
