We should feel so grateful.
I sure do. I never, never take that for granted, even when I turn on my own water faucet.
It would SUCK having to carry containers a mile or two to some river, take whatever water you could get out of it, and trudge back to your house with it...eh! (all those years of camping may have contributed to that thankfulness, too!)
And hot water from a tap on demand? When civilization goes down the tubes, if I am still around, I will likely shed tears each and every morning when a hot shower is not an option. Man, I love a hot shower.
When I was in the USN, they limited us on the ship to a “One Minute Shower”, and the Shower Police would walk by and bang on the shower if you were in there too long.
I resolved that, when I got out, I would take hot showers as long and luxuriously as I wanted to!
