The Great Oz replied with some of my thoughts on that saucie - to which I'll add - there is no key. I'd have to lug around bolt cutters. The fact that I do not (and would not carry the key if it were a padlock sealing the collar) is a less overt sign of my commitment - that fact that I do not have the means of her release at hand indicates I do not treat her commitment lightly. My regard for her is a much more overt sign of my commitment - and something I do consciously - and therefore is something that has much greater meaning to both of us
