We moved into our house in South London in February. Previous owner was downsizing and moving to Surrey, so, not round the corner, but not the other end of the country.
About once a month, she will come and park up outside our house. I think she then goes and walks her dogs in our local park. The first time I was going out and just said a quick hello, and she commented on the changes we've made to the house. Nothing rude just "ooh, it looks very different".
I think she's outside now. I want to pop out but I'm waiting for her to go first. I just find it really weird, and a bit invasive! I don't want to encourage friendship with her, etc.
It is odd, isn't it?
