Rice and Cakes

As a little child playing with sand and clay,
I cooked sand as rice and molded clay into cakes, pots and animals.
We exchanged stones-cum-eggs for paper-cum-money
And it was pure fun.
Little did I know that I would ever be paid for playing with sand and clay,
Little did I know I'd one day work in a kitchen
Where the only things we cook and serve are sand and clay
Only that now they are consolidated into rocks.
Yes, I am a geologist, working as a mudlogger.
