The students (upper ints + probably) create a scene in which each line of dialogue begins with a certain letter of the alphabet. Traditionally, the game starts off with an “A” line.
Are you listening to me?
Baby i'm always listening to you
Can you not call me baby!
Does it matter, I thought it was romantic...
With a bit of practice it does become easier and is great for on the spot thinking.
Maybe you could mix up the letters / start elsewhere in the alphabet.
