((((Sunny)))) You did the right thing. You have handled this situation the right way from the get go, even from when you called to find out your responsibility/liability if anyone were to get hurt. I am sorry your neighbor got offended. It is not the same world it was, even from when your daughter played on their swing....that probably has more to do with his reaction to your message than anything.
My looney tunes neighbors stood outside in their driveway screaming at each other last night. Went on for quite a while. Scott was outside, and another neighbor went outside and stood there with his arms crossed, never said a word, just stood there watching them. Then they decided it was time to take it inside.
They do this pretty frequently. I think they think if they are outside, their kids aren't hearing them...but if we can hear them, their kids are hearing them!! (Who stands outside airing all their grievances for the whole neighborhood to hear?!?)
Takes all kinds to make the world go round, I guess.
