HOLD YOU TO THAT

I WILL TAKE YOU AT YOUR WORD

You tell me you can learn Chinese in two years? I will hold you to that. (promise)

or

"So you had better listen to me, because I swear, if I should fall before the end and you don't seem to be doing things properly, I'll get up again to give you a good finger-wagging."

"I'll hold you to that promise."

"You know, I think you'll be all right, even without my help."
