Water isn't actually wet, but it makes whatever it comes into contact with obtain the property "wet". Let's say you put a slice of bread into water, that would make the bread wet. What about if you poured water onto the bread? Yeah, bread would still get wet.
What if you poured water into water? Nothing would happen. Water is water... it cannot change itself with itself.
I don't know why a lot of people have a hard time with this simple dilemma.
