Water Bottle

One foot tall it stands,
Deep blue like the depths of the ocean,
Silver like the shining stars above us,
Your reflection shines back at you,
It holds cool and hydrating water,
Something many people crave on a dry and hot day,
It take it everywhere like a best friend,
Rely on it in the hardest of times,
It is a vessel of safety for so many people,
Yet unavailable and restricted to so many societies,
So many variations,
But I will carry only one.
