I think most people in America don't realize how good we have it when it comes to water. Especially now with all this filtered water; we get spoiled.
When I was younger we didn't have water filters, I drank tap and to me it tasted fine.
Now I'm drinking from a Brita filter and I'm addicted to it. If I drink tap I immediately taste it and I'm put off, not wanting to finish it. There's nothing wrong with it, I'm just picky about the taste of the minerals inside it. It's crazy to think about it when you can't be bothered to drink average tap water when there are countries out there who would literally kill for it.
