"Who am I", the sign is clear, but perhaps unnecessary, the trip dipped suddenly, the change was good

"The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping herself before she found herself falling down"

"In another moment down went Alice after it, never once considering how in the world she was to get out again"

`Well!' thought Alice to herself, `after such a fall as this, I shall think nothing of tumbling down stairs!

The Caterpillar and Alice looked at each other for some time in silence; at last the Caterpillar took the hookah out of its mouth, and addressed her in a languid, sleepy voice, Who are you? said the Caterpillar."I hardly know, Sir, just at present- at least I know who I was when I got up this morning , but I think I must have been changed several times since then..........................

2007 might have had some sharp edges around it. The trip was different. The fall may not have been down at all. The question of "who we are" dulls with sharp edges. The posted signs may have nothing to do with the trip anyway.
