The Experiment

I'm at a college. A professor is doing an experiment. three people, me being one of them, have to drink three glasses of water. person one takes a sip then spits the water into a trashcan. person two is required to drink half of each glass. Person three (me) has to drink all three full glasses. Afterwards, person 2 and I need to use the bathroom. As we are at the urinals a lady walks in interupting our peeing. person 2 freaks out and runs into a stall to finish relieving himself. I have to go so bad I don't care and just keep going. It's then that I realize the experiment was to see how much one had to drink before they didn't care who was in the bathroom. and then I woke up.
