Staying on the horizon

If it was with us on the beach
It would be the beach
But it's on the edge of the horizon
So far out it's not
Possible to tell which way it's headed
Without more patience than I possess
It's certainly not possible to give advice on
Barnacle removal or
Mess hall protocol
Because it's not on the beach
It's not the beach
It's not my whole life
I can even make it disappear with just my thumb
Unfortunately all grandparents aren't content with the thumb maneuver and
Although we aren't on their beach
There is no place to anchor that is out of sight or
Out of reach
