So, excuse me while I try to calm down..... it has only just happened you see! 
. Usual scenario,, busy residential street, school run parking at a premium. I always scrupulously avoid parking over residents driveway exits where there is a single dropped kerb. I have just been told off by some van driver's wife (house has four cars parked out front) for parking over part of their double dropped kerb. Their kerb is twice the size of everyone else's, no doubt to feed their car collecting fetish, but my point is, as I made politely to her, that I had left an exit for her. It just wasn't the one she wanted to use. I know tempers get inflamed at these times, but our local situation is terrible, and I try my best not to upset anyone. I used to live on the same road, it's a small community, and I don't want to be unreasonable but this woman was so condescending and entitled and told me off like a six year old with a toileting problem. If it was a question of access for pushchairs, wheelchairs or the blind it would be different. Why should she assume she can have two free spaces on the street outside her house when everyone else gets one? I am looking forward to tomorrow's parking battle
