  Really? I've seen a lot of people do it. That's exactly why I upvoted.
context: Not unpopular >
  
  As the one who pays the water bill at my house it's (disproportionately) infuriating. I don't even need water to dampen the brush before I start. >
  
  Not once in my lifetime have i seen or heard about people doing that. Do you live in a "special" region of the world or where did you whitness this so frequently? >
  
  i mean this is 12 years old. I sure hope minds have changed enough to not keep the tab running for 2 minutes for nothing. At least that it's not a common thing to see nowadays. >
  
  I stopped doing it when I saw this on TV 30 years ago. Anyway, how could you possibly know how common this practice is today? >
  
  Wait, people actually do this? I knew a lot of people aren't very bright in this world, but really? Don't some places charge you for how much water you use? >
  
  Nah. I also don't know anybody that does this. Definitely popular opinion >
  
  Nobody does this. This is a popular opinion >
  
  I only do this when it's cold and my water takes forever to warm up because the really cold water hurts my teeth >
  
  If you knew how much virtual water you use in a day you would be less concerned with such irrelevant shit.
  Edit. Your cup of coffee used up 140 liters alone so who cares about those 5 liters when brushing your teeth? >
  
  Virtual water? >
  
  Wikipedia >
  
  The sound of the water hitting the surface is part of the brushing process. It completes the morning and night rituals!! >
  
  That's unpopular? Who the fuck even does that? >
  
  People do that??? >
  
  How is this unpopular >
  
  Flushing the toilet after a piss is where the real waste is. >
  
  I run it until it's hot. Takes a bit. Also, there's no such thing as "wasting water", it doesn't disappear. >
  
  You need hot water to brush your teeth? >
  
  It really depends on the water supply - if you live somewhere with an abundance of fresh water then it doesn't really matter all that much. >
  
  Upvoted for unpopular and also because I agree. Never understood why people do this >
  
  You just upvoted a popular opinion. Nobody does this
