As I was walking through the corridor to the library, one of my Y10 students smiled and said, “See you later’ alligator!”

I stopped her and asked if she knew the difference between an alligator and a crocodile.

Three Y3 girls nearby listened with interest. 

“Not really,” she said, “What is it?”

I answered with a grin, “One will see you later, and one will see you in a while.”

She rolled her eyes and groaned, and then one of the younger girls said, very loudly, “I don’t get it.”

“Yeah!” said one of her friends. “That’s a dumb joke.”

The third little girl, with a look of grave admonition on her face, said, “Teachers shouldn’t tell jokes when it sounds like they’re going to teach you something good.”
That’s me. Failing since 1.05pm today.
