answer:I will accept your experimental results on the grounds that I have not yet sired any children. As long as the coupons only count when the children are with you, I don’t see how anyone could reasonably complain. If you want them to be good elsewhere, however, then it seems you would have to broach the topic with anyone else who you wanted to accept them. You can’t decide what the rules of someone else’s household are, after all, and I think it would be reasonable for someone to be upset if you tried doing so without consulting them.
