The Mystery is like a big black dog, off leash.

Sometimes it cavorts around you as you walk, amusing you or annoying you depending on its behavior.

Sometimes it comes at you running and lays you out flat.

Sometimes, like today, there you are, minding your own business and it jumps up onto your lap and sits there, way too heavy and way too big.

You can't tell it to go; it won't.

So just relax under it and know that it will, eventually, of its own accord, find something else to do.
