Kinder Transition Days

Liem's attended all four Kinder Transition Days at his school and is really looking forward to starting school. Here is something they had the kids do..."Circle the pictures of things that make a noise (sound)".
Liem: I saw a boy circle a chair. Chairs don't make noise!
Mummy: But Liem, you circled the apple and the lamp...
Liem: When you bite an apple, it goes "crunch". When you turn on the lamp, it goes "chk".
I guess he has a point...
