Why do neighbours think that when you offer a few veggies from the glut in the harvest or the offer of giving something away you no longer want and they can use such as knitting pattern as an invitation to "pop in for coffee" anytime they wish?
How do you go about deterring such neighbours?
To me you are sending a very mixed message here, so no wonder your neighbours got the wires crossed!
Why would you offer a person you did not want to get to know better surplus anything? You could have driven down to the nearest food bank or soup kitchen with the surplus from the kitchen garden and given anything else to a charity shop. No strings attached there.
Surely, it is only natural to see the offer of such things as an attempt to become better friends with the neighbours?
On the other hand, it would have been politer of your neighbours to ask you in for coffee than to pop in to your house. I mean they have already had a gift of your garden produce, so giving you a cup of coffee is a minimal return.
Nor, do I understand, why if someone comes by and invites herself in you don't politely say it is an inconvenient time, as you are working, just going out, etc.
