Not flushing when you, umm..... pee....takes a bit of getting used to, it's almost a reflex habit for me, but I'm Growing up in Vancouver, I don't think I ever thought there was such thing as a water shortage....it rained basically all the time out there. But when you start to think more globally, you become more and more conscious of water waste, and shortages in places, so every little bit counts, right! That said, it takes a bit of getting used to not to flush when you...umm...pee. It's almost a reflex habit for me.
