A teeny tiny pin prick pricked
And so the skin grew thicker
And two more pricks there pricked their prick
And so the skin grew quicker
And rise in weight and temperature
The skin began to callous
Till all the pricks were no more felt
The skin fell numb save malice
For skin too thick can turn itself
Quite into what it fears
A tiny prick will come and go
But skin can last for years
