I think we've got really good neighbours. We all take parcels in for eachother, have a chat when we've got time and keep an eye on eachother's properties. One of my immediate neighbours is hardly there but will feed our cats if needed while we're away. Our other immediate neighbour has the key all the time, we take bins in for each other, take deliveries of parcels and larger goods, water plants while away and they are my first port of call for feeding my cats and look after them really well, making sure they see each every day and popping back in if they haven't.
I know this takes a while to build up, but we're about to move and I know some aren't so lucky - had to drive 5 miles to put my sister-in-law's bin in last year as she didn't feel she could approach a neighbour.
