Moron convention, our place, today

Today, we've twice had knocks on the doors from people looking for various people I've never heard of. The first one, it emerged, had got the right house number but the wrong road, and left quickly enough when I corrected him. The second one when I asked if he was sure he had the right road initially told me a different road from here and then changed his mind and decided he was on the right road (despite the total absence of the person he was looking for). I guess there should be a third idiot along any time now...
