Or when the new neighbors show up, you could very politely (and I am not being sarcastic) take them a "welcome to the neighborhood" treat of some very local deviled eggs. Or brownies + 1/2 dozen eggs to share. Could it possibly be that some other neighbor complained? So it could still be a good idea to start off on the right foot if possible.
What could I bribe you with (LOL) to get A blackberry bush in the mail? Besides my forever gratefulness...
