I always call round to see my new neighbours, not that we have very many, most neighbours stay just that, neighbours. Very few houses for sale in our area. I take them a card to welcome them and perhaps a bottle ****. I have made very good friends with a relatively new neighbour, who comes to visit on a regular basis, because I have fresh mint growing in my garden. She picks bunches of it, and takes it over to Spain to make fresh mojito ********* when she visits her s/o. I have now taken a cutting of the mint plant, and will present it to her when it begins to grow again. I also invite my neighbours whenever I am holding a party. It is better they are in my home than knocking on the door complaining about any noise LOL
