Teacher Chen: OK. You four students didn't hand in your homework today. Can you tell me why?

A-sing: Well, my dad forgot to put it in my backpack this morning. You should talk to him!

Bau-shan: My mom wasn't home last night and she usually does it for me.

Chia-how: As you all know, it was very windy this morning. I was walking to school and my homework just flew away!

Lan-mei: Mine fell out of my bag and a dog took it!

Teacher Chen: I don't know whether I should laugh or cry. I can't believe I'm hearing all these ridiculous excuses!
