Water Recycling

The other day I was getting a glass of water from our water cooler when my step-mom's dog walks up and shamelessly starts drinking the water straight from the nozzle before it hits my glass. As grossed out as I was, I wondered how many times he'd helped himself that I wasn't aware of. Ten minutes later, my dad who had previously laughed at me, was going to the bathroom with the door open when he yelled at me "he's drinking it on the way out too!" Gross.
