A cup can be fragile and easy to crack
Some are glass cups and easy to shatter
Some are harder cups.. harder to break
But also harder to tell whether or not it's still use-able if beaten
Like a hidden crack that lets water leak
Water being life energy
An outside source of strength
A necessary nutrient to survive
Then there are those cups that can never be broken
Even if they have been dropped, thrown or beaten
Those cups you should treasure forever
As they best hold everything a person could need.
