Hi, I am having trouble finding the German translation of an English expression, "to hold someone to something", with the meaning that you would expect someone to deliver on something they promised. To be specific, someone made a very generous offer to me. I would like to acknowledge his generosity, but at the same time I don't want it to get awkward between us if he does not deliver on his offer in the end. Therefore I would like to make it clear to him by saying "I will not hold you to it." Thanks in advance for your help!
