Thirsty?

Several thirsty people stood around a table that held a glass of water. “That’s a vetro di acqua” said the first, pointing to the glass, “it must be picked up with the left hand.” “No, it is a verre de l’eau!” said another, " I have a book that says it’s a verre de l’eau and that it should only be touched with the right hand" “But my book says it’s a glass wasser” said the third, " and it must not be touched." “Well I am sure that it is a glass of water”, the forth said, “and I too have a book that proves it must be held with both hands beyond a shadow of a doubt!” As they argued another thirsty person joined the circle, picked up the glass and drank the water. Does it matter what we call a glass or water so long as we can drink? Does it matter what our sacred books call a drink or descibe how it must be dunk so long as thirst can be satisfied? If we find ourselves arguing over who is right while people go thirsty perhaps we have chosen to argue over the wrong things.
