The Automatic Faucet

I don't think public restroom automatic water faucets are automatic at all.  They don't turn on when you need to wash your hands.  No, I think you have to surprise them.  Because when you first walk up to them, they're like, "AH!  Someone's here!"  And they squirt water uncontrollably for a moment.  Ten seconds later, you've got your hands all soaped, you put your hands in front of the faucet expecting it to turn on again.  But the faucet's like, "Nah, nah, it's cool.  I know you're there."  So you try moving your hands around.  Of course that doesn't work. So you try stepping to the side for a second, and putting your hands in front of the faucet again.  But the faucet isn't blind.  It knows you never left.  So you hide in the stall again and come out.  But the faucet's used to your presence by now.  So what you finally do is just leave.  Walk out of the restroom.
...and then quietly crawl back in, hide in front of the sink, wait there for a minute, and then, all of a sudden, you jump up and shout, "BOO!"  And be sure to stick your soapy hands under the water gush.
