A: Did you get my WeChat message yesterday?

B: I did. Sorry I forgot to answer you. Was it important?

A: I can’t believe it! I got left on read!

B: Sorry, I didn’t mean to leave you on read. It’s just I was in the middle of watching a new episode of “Ozark.”

A: Well, the next time I want to offer you free tickets to a concert, hopefully you’ll reply and not just leave me on read!

Note: Being “left on read” basically means that a message you sent has been read by that person, but they haven’t replied. The expression dates back to at least 2016, when it was inducted into Urban Dictionary.
