This has my name written all over it.
My lovely NDNs have one parking space, we have two. They continuously park so we can't use second space.
They are also pissed a lot of the time, and go into the garden in the wee hours to have shouting matches, and allow their child and nephew to play in the garden, talking anywhere up until 4am.
There is also a lot of banging on the walls, and fair amount of fights going on at odd times.
Besides this, their daughter often follows mine into the garden, talking of how "wonderful" her 10th Birthday party will be, and everyone but my DD will be invited (this party will never happen, and I did feel sorry for her, until it came to my attention she was trying to make DD feel jealous)
We were quite friendly with them, but it became a habit that we were awoken by their fights-final straw was one about ndn and his sister both arguing about cocaine and being very drunk, then NDN felt the need to run down everyone she came into contact with, coupled with the fact they were general scroungers....they took complete offence to the fact we tried to inch away very, very slowly...things have just gotten worse and worse over the past year.
