Kim this is a toughie. How I would proceed would depend on the type of people they are. Some people are just careless and some people are just plain rude. If they are the kind of people you feel you can approach I certainly would say something.

On the other hand, some people could turn the whole thing into an *issue* against you and be very hurtful for the entire rest of the time that you live there. I lived next to some awful neighbors until they finally moved a few years ago. I did the dance of joy when the left. We didn't even speak for the last few years they lived here and believe me it was very stressful.

Also, some neighbors might even carry a grudge and do something to harm your property or furkids. There are sickos everywhere. I think my response would have to depend on the "reading" I get from these people.
