Our neighbours next door stopped talking to us about four years ago (well...her four years, him about six months ago), but we've never worked out exactly what went on.
Nothing happened, she just wouldn't stop and chat any more. They do weird things like if they're going out at the same time as us we've seen him peek round the corner of the house to make sure we've gone 
DD1 saw him doing it and we both turned to stare at him, but he just stayed there, peering at us
We don't want to ask them outright because a) by not saying anything to us they've not made it any of our business/responsibility b) don't want to get into an outright dispute with them c) we're unsociable so couldn't give a rats arse what they think.
But I came across this last night (especially like the sophisticated 'We can hear you having sex' ) about the rise of PA wi-fi names and thought it could be the answer to our curiosity?
Got any ideas how to word it? Obviously can't be too explicit because all the other neighbours would be able to read it, so wouldn't be able to come outright and say 'WTF have we done??'
Maybe it'd give me a few ideas if you were to tell me what you'd say to your neighbours through what you named your wi-fi connection?
