The blame game. Parramatta, NSW, Australia

I was in Parramtta yesterday and I visited an old sadly neglected historic cemetery from the early days of settlement, where I came across this gravestone. 

Gravestone in Parramatta

The epitaph reads:

Sacred to the Memory
of
SAMUEL BARLEY
son of SAMUEL and MARY BARLEY
Who was unfortunately drowned in a
Well on his Parents Premises the 23
Day of October 1834
Aged 3 years and 7 Months
The Well having been left uncovered
By a careless Female Servant who
had Charge of the Unfortunate
Infant who was a beautiful
Promising Child

Weep not for me my Parents Dear
I am not Dead but Sleeping here
My days are past my grave you see
Prepare yourselves to follow me
