I was just posting in the "I hate other people's children" thread about the way the neighbours complain about our dog's barking, when their horrible children run riot, making just as much noise all the time.
Is there anything you've got on your neighbours? Do their children play right outside your front door and do your ****ing head in, do they park their cars in your spot, play loud music, have parties - anything? Cos my mum's scared this mother's going to complain to the council about our dog. And next time I hear her moaning about my dog's barking, I'm going to tell her my dog will be silent the day her children play silently.
Alternatively, and this must be the most tempting option, tell your neighbours what po-faced miseries they are. We don't have a cat. But other people's cats wander into our garden and garage - we end up with pawprints up and down our windscreens, and yes - cat **** everywhere. It is a fact of life, and far worse things happen. These people need to GET LIVES.
