We live in a cul-de-sac with about 15 houses in it and for the last 3 years, a car (think Fiat Panda) visits the street every weekend and sometimes midweek around 10-11am. It's a disheveled male, late 60s driving with the windows down and he's always smoking a cigar. He comes into the cul de sac slowly turns round has a look at the houses and then drives off and carries on in the same direction he was going so doesn't use the cul-de-sac to turn around! What could he be doing?! Initially I thought he might be collecting things people leave outside their houses but when stuff is there to collect he never takes it. He always has the seats down in the car and from what I've seen there's nothing in there. Today I managed to catch him turning round in our road for the second time this morning and went out and asked him if he was looking for something. He stumbled over his words and said he was looking for number 47 which is in the next cul-de-sac down and was delivering meals to old people. He then became flustered and drove off! 47 isn't in the next cul-de-sac down and given he's visited the street for 3 years or more you think he'd know that? So bizarre but there must be an explanation, what could it be?
