Just don't move here because we have water restrictions and that would cost you big :p there is nothing wrong with it, a higher water bill maybe but nothing really wrong, people are addicted to different things, it could be much worse
Maybe you like water, maybe you like feeling clean, maybe you like the ritual of it, maybe you just like bubbles. But you're not alone!! I love it too and probably shower more than most! But I own a handmade soap company (e-MortalBeauty.com) so at least I can justify it as research. HA!
