Howdy from up North! I am reviewing your piece as a part of "The Kiwi Review Challenge! - closed" 

Great imagery and use of internal dialogue in this childhood reminisce. Your language is full and vivid. You paint a realistic scene with a natural ease.

This otherwise excellent piece does have a few errors. My suggestions:

You seem to be unsure on the tense in this... it wavers back and forth between past and present

'went to his usual spot where he would dive from in a minute' reads somewhat awkwardly and may benefit from a re-working.

You have a really great line with 'I followed closely behind, in my own clumsy way.', and in 'He straightened like a candlestick and fell, fell, fell...'

The comma is unnecessary in the line 'was a child, her'
'paranoid of submerging her head' may flow better as 'paranoid of being fully submerged'

'Determinedly I climbed' shoud be 'Determinedly, I climbed'. The second 'climbed' in this sentence feels repetitive. Would another wording work?

'my leg was shaking' shoud probably be 'my legs were shaking'

Great ending to this inspirational and encouraging piece. Thankyou for sharing. Write On!

My review has been submitted for consideration in "Good Deeds Get CASH!" .
