There's four adults live next door. Two parents and two older sons (about 21 and 25). Each person has a car EACH. That's four cars. They have a drive for one. Three are on the street. Even though they're in the same house, nobody ever parks in front of their own drive, it would be FAR too much effort to move one of their cars to get out of drive. So they park two cars outside my house. I don't drive myself, but my DP does and I also get taxis, shopping deliveries, etc delivered, and nobody can ever get near my house for next door and their bloody fleet.
Am I being unreasonable it really really bothers me? When DP came the other night, he managed to get behind one car because the other one outside my house was out somewhere. I almost opened the door and shouted out to him, "Have you asked next door if it's ok to park outside my house?"
