Depends on the neighbour.
In my first house, the old couple next door was so intrusive. We had a decorator in not long after we moved in. After returning from taking the baby for a walk, our decorator told us a weird woman keeps putting her hands up against the window to watch what he was doing!
The old guy would lean on the fence and watch me hang the washing out. I came home one day to see my washing was gone from the line... Next door had 'kindly' took it in for me and folded it all, underwear included at the top of the pile, and was sitting on their dining table. It wasn't even due to rain...
After trying to pull away from them slightly, they turned awful. They turned the other neighbours against us, who allowed their grandchildren to kick a football against my house. Banging on our door very early one morning accusing us of stealing their wheelie bin?! They could see clearly my front and back garden, so no idea where they thought I'd put it, especially when it was bin day morning, my bin was still out and they'd woke me up. Mental.
It took a few years to get friendly with these new neighbours. One is no bother at all, we bring each others bins in, it just naturally started happening. We talk minimally but friendly if we see eachother by the back doors.
The other neighbour is abit over friendly. She'd consider us friends and so would I, to a degree. But she would pop up at the wall to make small talk or to gossip about other neighbours.
90% of the time I'd have to listen to see if the coast was clear before I went out. Now I've put up some small trees against the wall but slightly taller than it so her view of 'catching' me is limited. But they're friendly and our husbands help eachother out, he's aging but knowledgeable and my husband is younger and knows abit but not as much as neighbour husband so it works well. But they do overstep sometimes and I wouldn't trust her to be civil if we fell out...
I'm looking to move in the next few years, terraced life isn't for me, somewhere with a private garden and hopefully private but civil neighbours 😬😁
