I reckon its a great idea to break down the bridges with your neighbours, with no strings attached, but as an opportunity to get to know who you each are at least. You never know they may get along with each other too and just need someone like yourself who is open and brave enough to make the first move. Perhaps invite them all to a morning tea at your house one day or at a local cafe. Even if only one turns up, you will have broken the ice or at least given it a go.
