  This answer so confused poor Alice, that she let the Dormouse
go on for some time without interrupting it.

  `They were learning to draw,' the Dormouse went on, yawning and
rubbing its eyes, for it was getting very sleepy; `and they drew
all manner of things--everything that begins with an M--'

  `Why with an M?' said Alice.

  `Why not?' said the March Hare.

  Alice was silent.
