I live in a small cul-de sac and each house has their own driveway (which can fit around 2 cars each). Some visitors have been really inconsiderate at times and literally parked in the middle of the street (despite there being space on the road outside as it is a long road with plenty of on street parking available) so nobody can get in/out. There has been a few incidents where I've had to park on this street as I've not been able to access my drive.
For example, today I came home from work and there was a car parked in the middle of the cul-de-sac again, dropping off my next door neighbour (who I do get on with). She was half parked on my neighbours drive and half on the street, but blocking my drive. I pulled in and sat there for a few minutes, and could see them both sat there talking. They didn't attempt to move (all she had to do was drive forward onto the drive. She would have had to of done this any way to get out unless I'd reversed all the way out to let her pass me) so I honked my horn to make them aware that I was there waiting. They still didn't move and just continued to talk. Not knowing how long they would be, I reversed out and ended up having to park across the street again and walk down to my house. As I was passing their car they both looked at me and smiled, completely oblivious to the whole situation 
. I had to bite my tongue.
As she was reversing out, I walked up to move my car and she just looked at me again but didn't bother to apologise.
Was I impatient and being unreasonable, or were they rude?
