P*ss off and don’t be bothering me

She could have danced the conga up the driveway to the door, and I wouldn't have noticed. To her, all I was was two legs. She didn't even have to walk by me or over me - I was on the far side of the car from the route to the door. She doesn't need my permission to put a leaflet in the letterbox. She didn't phone any of the other neighbours beforehand to ask if she could put one in theirs. It's not Texas where she'd be afraid she'd be shot for being "on my property" unannounced. I don't know, I'm just baffled.

Here's another one - but I was very nice and helpful this time.

Out for a walk with the dog yesterday, just around the estate. A car stops on the other side of the road, and calls me. So I have to pick up the dog (excited puppy) and walk over to her. She's in the car with her teenage daughter. They ask "is this such an such a place?". It is, I say, but that's a very big area (a whole suburb of a town, basically). Do you have an address? "No", she says "Just an Eircode".

Of course an Eircode should lead you exactly to the house you're looking for.

So I ask for the Eircode, thinking I'll look it up on my phone.

The teenager then proceeds to show me her phone. She's entered the Eircode on her Google Maps app. It's showing up on the map. Her location is showing up on the map. You can see that the place they're looking for is on a road directly parallel to the one we're currently on. But what these geniuses haven't done is hit the "Directions" button that would give them accurate turn-by-turn instructions - both in text and by audio - on how to take two right turns to get to where they wanted. I wasn't under a car, so I put my incredulity aside and just helpfully and cheerfully directed them, like you'd talk to a toddler who can't find the teddy they just dropped behind them. "There he is! There's Teddy! He's behind you love! No, not under you, just behind. Look..."

It's unbelievable to think that such people walk (and indeed drive) amongst us.

I've recently decided that I choose who I engage with, not other people.

So in the OP's situation I would choose not to engage, at all, completely ignore them and simply get into my car and drive off as if they weren't there.

This has the double positive of:

A) Avoiding any hassle

B) Annoying the Karen (Especially if you get the bonus point of "Excuse me, I'm talking to you")

Also works when you park in spaces reserved for people with disabilities. It really annoys them when they get blanked. I saw the videos on YouTube, and apparently the male ones are known as Kevins.

You need to grow a pair and not rely on your family members to say something. I wouldn't tolerate strangers parking in my driveway irrespective of if I owned a car or not.

Seven cars is impressive, and rather exclusive. Stats from 2016 Census.

Meath had the highest proportion of households with at least one car (90.3%), followed closely by Cork County (89.0%). Meath also had the largest proportion (43.3%) of households with two cars. Cork County had the largest proportion (7.7%) of households with three cars while 1.8 per cent of households in the State had four or more cars. 

I always thought they were being encouraged by not meeting immediate resistance

But I was discouraged many times from acting on it with admonishments such as...you don't know what that person is going through or they could be lunatics and they might kill you etc

I’ll keep this in mind for the other bulb.

His friend can just tell the neighbour that the op has Tourette's, he shouts insults at everyone. 😉

Get a new car where you don't have to go through that rigmarole to change a bulb. Otherwise it will just keep happening.

You were spot on OP, the very fact the neighbour had nothing else to do than sit by the window waiting for you to return just to moan was justification for telling them where to go.

If you have gates keep them closed, can't see them opening your gates.

Or else put some flower pots across the entrance that can be lifted for family members.

That should give the hint.
