The River's Regrets

The little river flowed downstream

Taking everything within it's reach

While the pebbles clung like a leach

All the salmons fought like a team

The river laughed with joy

As it watched everyone struggle to stay

But he knew there was a high price to pay

If he played them like a toy

Eventually the river came to a halt

As it poured quickly into a lake

The river realised his fun was done

And he thought it was all his fault

He realised he had apologies to make

The horrible thoughts weighed a tonne

This is an Italian Sonnet on a river that did things without thinking about the consequences. 

"All the salmons fought like a team" - It is a simile trying to show the effort they put into trying to get upstream. Line 8 has a simile as well, "If he played them like a toy" which is comparing the river to how a child plays with their toys often by tossing them around. "While the pebbles clung like a leach" is also a simile.

There is personification in line 2"taking everything within it's reach, line 5,"The river laughed with joy", line 6, "As it watched everyone"

There is a little bit of alliteration in line 11 and a metaphor in line 14, "The horrible thoughts weighed a tonne."
