Be sure to include an email with your message if you want me to write you back!
Mr. Slade!!!! You didn't answer my message!
Have you sent a message to Arthur Slade but received no answer? What happened? Maybe Art is ignoring you! Ha! More likely, you forgot to provide your e-mail address or the address you provided bounced when he wrote his witty reply.
Have a look at the dead mail to see if your message is there and to find out what you need to do to get it answered.
Unless Art is ignoring you, in which case don't bother.
