Water doesn't go bad.

Yes it does.

One of my pet peeves (Its name is Michael) is cups of water left around, half drunk, just waiting for those aliens from Signs. Oh, that movie Signs, too, that's a pet peeve. (Its name can be Helen Keller.)

The thing is, water left loafing in a car for more than a day, especially in the sun is quite unhealthy. Water grows mold if left out of doors for a long time. It's just not good to drink old water.

It's icky.

Remember Coyote Ugly? Remember when they yell, "Hello, no, H20!"? Yeah. That's a pet peeve too. (Its name can be Jersey.)
