We are all in the same boat.
Actually, we are all in separate boats; kayaks in this case.
But we are all on the same river.
And because we are all on the same river, the river is crowded;
Bumper to bumper or bow to stern, if you will.
And the wakes from all the boats passing send us up stomach-dropping heights —
And down again.
But we manage each to keep our craft afloat.
None of us flip over — or out.
We steady ourselves as best we can.
