Our next door neighbours are a complete nightmare. Over the past couple of years the mother of four kids ranging from an 18 year old boy to three girls from 10 to 13 in age had been going out with a violent, alcoholic and abusive guy in his forties.  They were shouting at each other every night usually about money, drugs or alcohol until around 1am.  We did complain to them and it would be ok for a couple of weeks and then gradually slide back to their normal routine.

Finally she kicked the guy out and we at last thought peace was around the corner.  Since december 2009 it has been a pleasure to be living in our house again.

However, now the hot whether is here and the abusive guy has moved out, the eighteen year old boy has started getting into the habit of having his friends around and sitting in his back garden drinking lager around a small bonfire.  At first we didn't mind too much as they would only be once a week or so, and usually by 11 pm they would all go there seperate ways and extinguish the fire.

As you can appreciate in this heat we need to sleep with the windows open at night. Whilst my wife used to go to bed at around 10pm she had been waiting until around 11pm to ensure they have left. Just recently these gatherings have been getting later and the friends appearing have grown in numbers.  This week seems to have become worse. Every night apart from Thursday there have been these "garden parties" involving a dozen 18 year olds drinking and swearing until the early hours. I must stress that they are not massively loud, but they are loud enough to wake you with a sudden laugh or shout.  The teens do seem to get quieter the later it is, but not quiet enough to sleep through with our windows open.

As you can appreciate it is difficult to approach a dozen young "boozed up" lads at 1am without fearing a brick through the window. 

The mother is no use at all and simply can't control the 18 year old lad.

Any ideas how we can stop this?
