Dilbert: Did you finish the specs I asked you for last week?
Ted: You didn't follow up with me on that, so I assumed you didn't need them.
Dilbert: I didn't need to follow up. I asked for the specs by today, and you said you would have them done.
Ted: Yes, but then you didn't ask me again.
Dilbert: There was no reason to ask you again.
Ted: Obviously there was a reason because asking me once didn't work.
Dilbert: Can you finish it by next week?
Ted: As long as you follow up.
