Safe Travels.

Pretend that we are upon a beach, walking towards where the waves break, shoes in hand. Tell me, what would be beyond this shore?

Don't know the answer?

I'll tell you. It's another shore. Quite simple, really. What's beyond that shore? This one's not much harder: it's just a further shore. And what would be beyond that? A still more distant shore. This could go on for quite some time.

So, what's beyond the second-to-last shore, I ask?

An edge? A cliff? An endless precipice into the vastness of the universe?

Nope. It's the shore you started on.

Don't believe me?

Then you may climb into a ship, if you wish, and set out to prove me wrong. I'll stay here, tracing short-lived letters into the sand, while I watch your ship slowly sink over the curve of the horizon.

I expect to hear back from you, eventually.
