An elephant’s faithful, one hundred percent!
言行一致
gen.kou.i-.cchi
Literally: speak – go/act – one – do
Alternately: One’s words and actions are in accord. Doing what one says. Walking the walk as well as talking the talk. The opposite of hypocrisy.

Another moral of the story is, think about whether you’re truly willing to see something through before you promise to do it.
