"It is the time you have wasted for your rose that makes your rose so important."

"Men have forgotten this truth," said the fox. "But you must not forget it. You become responsible, forever, for what you have tamed. You are responsible for your rose..."

"I am responsible for my rose," the little prince repeated, so that he would be sure to remember.


- The Little Prince


note:
the meaning of 'tame' in The Little Prince,
as explained by the fox,
is "to establish ties."
