Learning to read - sister's bus (AVI-Start)

Sister goes on a trip with her bus. Does Piet fit in on the crowded bus? And who else will they meet along the way? Funny story about a pleasant trip on AVI Start. Every beginning reader in group 3/year 1 wants to show how well he can read. How nice is it to show that with this recognizable story full of short words and simple sentences? That's a nice way to rack up some reading miles.

I'm tired of it, says sister.
I'm leaving.
what about me? says Pete.
you can come along, says sister.
but... does piet fit on the bus?
or is sister's bus already full?
