Guardian readers have known for some time how to stop AI systems from taking over the world (Robots say they have no plans to steal jobs or rebel against humans, 8 July). Simply keep them busy answering two questions: “When is the best time to make orange marmalade?” and “How many uses can you think of for a 35mm film canister?”

• For a short time, I took home-made sandwiches to the office for lunch (Do you take a packed lunch in to work? Perhaps that’s why you’re exhausted, 4 July). Their consumption got earlier and earlier, and I gave up when I polished off “lunch” as I drove into the car park.

• My husband was having a lunchtime pre-A-level tutorial with some of his sixth-form students. At the same time, he opened his foil-wrapped lunch. However, he had picked up the remains of the previous night’s supper for the cats. He solemnly ate the cold liver and bacon in front of them. I don’t think the cats got the cheese and Marmite sandwiches.

• I can trump Emma Beddington’s frustration at being asked for customer feedback on a tea towel (Stop asking me for feedback. How am I supposed to review a tea towel?, 10 July). When having ongoing treatment for cancer, I was sent a text asking me to rate my experience in outpatients out of five, and if I would recommend it to a friend. 5/5 but, well, no, not really.

• Perhaps the little boy who misheard the Lord’s Prayer as “Our Father who art in heaven, hullo, what’s your name?” was unwittingly on to something (Letters, 9 July).
