The water bottle

Standing tall, quiet, undisturbed
Quenching thirsts, holding liquid wealth
It fills up to fill me up
And empties out to fill me up still
It's grace and elegance unmatched
As it graces the side of my backpack
It's not loud, I oftentimes forget it's around
But anxiously search for it when it's time
It's not farfetched, just efficient 
It's my little water bottle.
