Throwback to that time where we received an email from a company we wanted to intern with but the person's name was not gendered so we searched for their account in social media and then we found them on linkedin. They were a guy. Except my friend's gaydar was going off so we wondered if we should put Ms. on the response email. We entertained putting Mx. too but the person might not vibe with that. So anyway, we ended up using Mr.
.... Anyways, on the next email we got from that person we were both addressed as Mr. (we're both GIRLS with very gendered names)
