Last year a lad who I would say is in his 20's moved in on the next street from me.
A few weeks later, I noticed a car park on my street, some bloke got out and walked around to the next street and went to the new residents house, 2 minutes later he comes back and drives off.
Then this would start happening daily or every second day, sometimes the same car other times different cars and different people, just parking on my street, then getting out and walking to the next street just to visit him for 2 minutes and then leaving.
Other times, a car would pull up and just sit there, then the guy from the next street would walk along to it, get in, the car would then drive all the way to the end of my street where the lad has just walked from, drop him off and he'd walk back to his house.
After about 3 months the routine started to change, people would only park on my street 1 or 2 times a week, however, I started to notice him going for 5 minute walks regularly, so I decided I would try and see where he goes... there's a church at the end of the street with a lay-by outside it, the cars that used to park on my street are now parking in the lay-by and he goes and sits in their car for less than a minute and then gets out and walks back home.
Other times he gets into his own car and drives to the church lay-by, then comes back 5 minutes later, he's had 4 cars in the last 6 months and always goes for the same model.
Sometimes he will go out to his car, sit there for 5 minutes making the brake lights flash on and off - then he'll drive off, first I thought perhaps he just has a wiring fault - but, he does the same thing in the other cars.
All the above can happen at random times, 10am / 1pm / 4pm / 7pm / 9pm / midnight right through to 3am etc.
Would this come across as suspicious if you saw it happening near you?
