f-mail
It’s like a private message on Facebook, but it’s more important. You send it to someone because you think they’ll actually read it. You were wrong.
I sent you a message. You didn’t reply. I’m not even mad. I’m just disappointed.
You had one job. You didn’t reply to my message. I’m going to haunt you in the comments.
You sent me a message. I saw it. I ignored it. You’re not worth my time.
