I am so glad I waited a day and let everything cool off. I called first and said we were going to stop by. We stood in the door and I handed them the two notes and the gift card (they didn't really look at anything, just took it). We had a very nice chat. husband was very concerned that the H would still be irate but he had calmed down. We told them we were working with-difficult child and they understood. In fact, the mom had specificially instructed the police to scare the ^(#*@*#$ off of difficult child and not press charges, and she said, "Did it work? Did they do what I asked?" Yes. And H added, "We love difficult child. The kids have grown up together. It's really sad we can't have him over any more." We agreed and thanked them. I feel like there's a bit of closure there. Whew.
