My neighbours have lived next door for about 6-7 years. Our houses are separated by 2 side walkways - so about 8ft apart. Theirs is a small 2 bed house, with a tiny garden.
When they moved in they had no children. They now have 4.
Their children are very noisy, especially when they all start screaming/crying. However as the older 2 are now school age this seems to have got a little better. And you expect noise...it's annoying (especially as I can hear it inside my house even with all the windows shut) but I figured eventually it would get better!"
However what is REALLY pissing me off is that for the last couple of years my garden is constantly full of their kid's toys. Now I have sons (they're now teens so don't really play in the garden) and when they were younger we had a few balls over the fence - BUT we always used to try and keep this to a minimum, tell the boys not to hoof it the length of the garden, under inflate the ball a bit so it didn't travel far, not play with small tennis balls because they'd always bounce over, etc. We weren't perfect but it was occasional rather than regular.
Their DC play very close to the fence between our houses. I'm not sure why, because the fence on the other side of their garden is much higher. And playing where they do, they chuck stuff over. Admittedly, they don't often knock to ask for it back - but that isn't the point, I don't want to have to go out and pick up kid's toys and chuck them back over. It's sometimes balls, but more often dolls, action figures, cars, all manner of plastic tat. I've not seen some of it before, and nearly broken my lawnmover when it got caught in the blades.
My garden is very large, and a mess. As such I suspect they all think it doesn't matter (like when they chopped all the overhanging branches off my tree last year and wedged them down the side of my fence - I know you're meant to offer the branches back, they didn't, just shoved them in my garden). Similarly, their refuse bin is ALWAYS overflowing, meaning the bags get ripped by foxes/other vermin and their rubbish, including their kids nappies, again ends up all over my garden.
There are many things I am prepared to pick up from my garden. A half chewed dirty nappy is not one of them.
I get their house is small, and so their children probably spend more time in the garden/ have more toys in the garden as a result. I also get that because there are so many of them, it's hard to keep an eye on all of them. Also that with 4 kids they probably generate a lot of rubbish every fortnight. But they have 2 cars and surely could take stuff to the local tip (only a mile away) rather than have their bin constantly overflowing?
There's a few other things as well - they broke the top part of my fence (the strip between our houses) which was trellis, and replaced it with crappy twig stuff, which looks shit. Oh, and they also chucked several binbags in my bin when I left it near the boundary of our properties.
Would this piss you off? Because taken as a whole it really annoys me.
