Dear Advertising Moron,

Why, yes, the water for my toilet and my tap do come from the same place. So does the water I use to wash my hands which I later lick chocolate off.

The great thing about living in a first world country is what that means is that the water in my toilet, like all the other water in my house, is fully safe to drink, floridated for the health of my teeth and generally over-engineered.

What that doesn't mean is that the water in my taps is somehow dirty or contaminated. It also doesn't mean that I need to buy a Brita to filter my already perfectly healthy tapwater.

The only thing involved in that advertisement that is full of shit is you.

Sincerely,
Me
