Is it a dinoSAW or a dinoSAUR?

One day, during my Secondary One Arts lesson, my Arts teacher asked the class Monitor to go to the Arts Storeroom and get him a dinosaur. Without any hesitation, he dashed out of the classroom towards the storeroom and all of us in the class were waiting eagerly to see the dinosaur.

After a long wait, he came back to class panting away but empty-handed, he stared at the teacher blankly and said, "Teacher, I could not find any SAW in the storeroom!" Some of the classmates simply could not control but burst into laughters. Apparently, he did not know what a dinosaur was and he felt so embarrassed when the class was laughing at him. But, the teacher just smiled at him and went to pick it up himself.

I think this is just part and parcel of lifelong learning. Who would dare to claim that he knows everything in this entire universe? I can be dead sure that even the classmates who knew what a dinosaur was might not know everything about dinosaurs. Knowledge must be acquired with humility.
