Even though Dylan can see the effects of a light bulb after flipping a switch, as the whole room is illuminated, still he must look directly into the bulb itself, in order to confirm that the bulb is the source of the light. And he must do so not once but each time the switch is flipped. Dylan takes nothing for granted.

Last week Dylan approached the box of tissues on Clare’s night stand, carefully removed a single tissue (yes, just one), blew his nose perfectly, and then threw the used tissue into a rubbish bin. He did this as though it were his ordinary behaviour every day. We were astonished.

Dylan says 'spider' ("bider") when he sees a spider and 'strawberry' ("trawby") when he wants a strawberry.
