Okay, have your answer?
Unless you said "running water", you disgust me!
Think about it. Yes, your smart phones and the internet are pretty technologically great. However, would you even want to touch the keys if you couldn't wash your hands, especially after using the restroom?
Oh, and forget it. You don't deserve a restroom. If indoor plumbing didn't immediately come to mind when I asked my question, you should be forced to do everything, and I mean everything outside.
Beyond the basic necessity that clean, running water brings to our lives think for a moment how integral those three molecules are on an emotional level.
Take away water from your childhood experiences, and purple popsicles and sprinklers in the park, pounding searing cement, would disappear. Floating on real rubber inner tubes in your uncle's upstate pool would be gone, as would bruised knees from slip-and-slides.
The inexplicable refrain of "hurry, put mud on it" as you got stung by a wasp yet again would not be heard, because nothing would flow from the green garden hose to mix with the dry, crumbly ground.
When your stomach hurt there would only be deflated red water bottles, and try gargling with salt but not its companion water when your tonsils swelled.
Cruelly, buttercups would wilt sadly in empty jelly jars, even though moments before their under-the-chin yellow glow helped prove undeniably that you indeed love butter!
Could we get by without water flowing freely into our lives? Of course. And while our smart phones and internet access would surely help pass the time, it seems to me at least that it just wouldn't be the same.
