Our neighbours who's back garden etc we sort of overlook used to be a family of 4, since last year ish I think, we haven't seen any of them, all the windows closed but curtains in place you can see the hand wash bottles by the kitchen sink as you drive past on the other side. So they haven't moved out, it's not for sale or been sold and not on air bnb I may have checked
A couple of months ago 2 men and a woman spent the weekend there, bbq going windows open etc. Then it seems they left and nothing for weeks then last weekend there they were again same 2 men 1 woman.
I think they're swingers dh thinks I'm bonkers.
Who are they?
