We have recently moved to a cul de sac with little parking and we quickly figured out that rather than parking a little walk away from the houses, people block cars in by parking across the parking bays. This was irritating at first because we did not know whose car was whose so had to spend ages knocking on doors but it seems that most people just honk their horns and sooner or later the offender will come out and move their car 
. Got used to it now so not too much of a problem!
Anyway today, I was off to do the school run (too far to walk before it gets mentioned) and there was a car parked right across mine which I did not recognise. So I honked the horn for a few minutes, then started knocking on doors but no one knew whose car it was. 15 minutes later, old man walks over. I say 'is that you car', 'yes' says he. 'I've been honking my horn for ages now' says I. 'And' says he. So my blood pressure went up to boiling point 
.
He said that people block cars all the time and he's visitor so whats the problem? I said that anyone with any decency would have left a note on their car to state where they were and he was extremely rude and arrogant and I would call the police next time. He also said he did not hear me honking but he was in the opposite house (the only one I did not knock because there were no lights on) so I would doubt it. I can imagine the old git was watching me and getting a kick out of it!
D H now thinks I went over the top and I have caused trouble with the neighbours . So it was OK for me to be late to pick the DCs up from school and I should not have had a go???
