Kim,
Your message is somewhat confusing because you seem to be addressing two issues.
When a child is in my home and is doing something wrong or causing problems and the parent doesn’t correct the child, I will. If the child’s parent is not there and the child doesn’t listen to what I say, I send the child home. (Of course I would suggest calling the parent to let them know you are sending their child home or ask that they come a pick their child up). I would also remind you while you may think your children never cause any problems, that may not be the case.
As for the “hurt feelings”, if you have rolled out the welcome mat to your neighbors and they do not reciprocate, you need to dust yourself off and make some new friends. Don’t make your home so accessible to everyone, all the time.
Blessings.....
