an interesting discovery

When I first arrived here, I was under the impression that the tap water was saltier than what I was used to but perfectly fine otherwise. Recently, I've come to learn otherwise. I was baking with a friend, and we needed some water. Naturally I went to the tap and filled the cup. My friend looked at my with a puzzled/shocked/disbelieving look on her face. I wasn't sure what I had done. She proceeded to tell me that I can't use that water for baking. Now I was the one wearing the puzzled/shocked/disbelieving look. Why not, I said. I've been doing it for a year! And not only for baking, but all my cooking and even making tea. She just about fell over. Apparently no one uses tap water for anything because even though they say it's clean, it's really not. She asked if I was worried about getting sick to which I merely laughed; after drinking the tap water for a whole year, I'm pretty sure it doesn't make me sick! Since then I've come across two other people who find my water drinking habits shocking. I guess I'll be buying more bottled water from now on! :)
