Question Author
Well I would like to say thank you to all who have replied but as most of you seem to want to put me down then I won't. I am not spending my day curtain twitchin but seeing as though I live not 30 feet from the house in question its hard not to see these things. I am not being neurotic but when 2 family members are taking a bike from the back of a lorry and the Police helicopter is about the so called disabled father runs out of the house and ushers the bike movers to keep it in the alley way and he keeps looking out at the helicopter its abit hard not to be suspicious. Not to mention its not just me who have noticed this behaviour.
On other occasions 2 people come to the house and one of them tells the other one to stay in a spot while the other goes to the door.
As for the horn beeping, the family member drives up the road, pulls up outside and with the engine running beeps once or twice ( maybe a code ) and then turns off the engine and gets out the car or even occasionally drives off. I have 2 kids myself and we have already had a drug dealer live on the street who had been arrested by the police for a string of offenses and so I do fear for the safety of my family if these new people are of the same ilk.
