Jenny was a bright pupil who asked a lot of questions.
One day she asked her English teacher why we ignore some letters when we’re speaking, for example the letter h in hour, honour and honest.
The teacher said, “We’re not ignoring them, they’re just silent.”
Shortly afterwards the lunch bell went and the teacher handed Jenny her lunch and asked her to heat it in the common room.
Jenny went to the common room, ate all the food and returned the empty container to the teacher.
The teacher said, “What happened to my lunch? I asked you to heat it and you’ve come back with an empty container.”
”But Miss,” Jenny said, “I thought the h was silent.”
