Having a couple of people over recently has led to me parking my car on the street outside a neighbour's house. Not blocking access (very careful with positioning), just "outside" their house.
Passive-aggressive note on car this morning: "Please show consideration to your neighbours and park in the space allocated to your house", along with a pair of wheely bins placed either end of the car about half an inch from the bumper.
Woman's writing. No one in at the moment, which is a shame as it gives me the perfect opportunity to point out that I've kept my mouth shut about their dog barking incessantly when I'm in the garden, and that if they didn't want cars parked in front of their house they should have bought one that doesn't have a road in front of it.
Can't abide cowardly note writers.
