Undercurrents

Beneath the plastered smiles,
Underneath the phony cheer,
You might see, if you look closely,
Undercurrents will appear.

They belie the placid surface
So all goers should take heed,
For a sturdy constitution
Is the thing you really need.

To avoid a true disaster,
Don't get sucked into the sea
Or the currents there will take you
Where you do not want to be.
