The environmentally responsible child

My son cares for the environment in a number of ways.
The first is by showering once a month at the most, to save on electricity, water and soap.
He also reduces the amount of washing up we have to do, by drinking out of the milk bottle and eating with his fingers.
He chooses to fertilise the garden, instead of flushing his nitrogen rich pee down the loo. When it comes to flushing the toilet, his motto is: "if its yellow its mellow, if its brown, let it sit there and stink!"
He also tends to wear his clothes to bed, saving loads of washing.

See, his mother may find it irritating, but he is just trying to do his bit for the planet.
grrrr
