(Strip Number 4151, Original Publication Date, 18 March 1982)
Panel 1: Having looked at Elly's sewing machine, Anne tells her that she had the tension wrong and there was some loose thread on the bobbin.
Panel 2: Her cheery declaration of "See? It's easy!" does not achieve the desired result of soothing Elly,
Panel 3: That's because she thought-bubbles "Why do people who can 'do things' always say that?"
Summary: Because they assume you have the patience to learn, you crazy fool! They also assume another thing that's not so; they assume that you don't regard being told to calm down as a humiliating pat on the head.
ETA: Lynn's latest banner visits yet another improbable and disgusting catastrophe on the long-suffering Irish people.
