When skimming flattened pebbles from the land
the angle of descent should be acute.
And never throw at row boats if they're manned;
but if you do it, do it quick, then scoot.but if you do, then then do it quick and scoot


When skimming flattened pebbles from the land
You can't fly kites up high, or race the dog
Those kinds of things should never be on hand.
'cos slinging stones should be a lonesome slog.apologies for changing this verse. I did it before I saw your intent. That hand line is awkward

At times of stress when nothing goes as planned;
if you have problems large, or by the score
when skimming flattened pebbles from the land
the buggers often sink into the shore.

So dig your toes into the sand below
and with the shiny rock at your command.
Let loose the missile, sling away your woe
when skimming flattened pebbles from the land.

Alright, alright I missed the point but the point is pointless. The poem is much much much better than the structure. Its a personal thing but I am not keen on verse that racks itself for no reason other than it is a good exercise. Still, a good exercise
Best,
