I was pushing buttons on the microwave oven today and after a little while the screen said “child lock” on it. Mum and Dad found it and they couldn’t make the microwave work any more. They had to go and get a book about the microwave to find out how to unlock the buttons again. “Child lock” must mean that only children can use it. That’s why I could lock it but Mum and Dad didn’t know how to unlock it. I think it’s nice that the people who made the microwave put in this special child lock just for me.
