My neighbour has bought a brand new, fancy looking moped. They've parked it right in front of their house, chained to a lamp post. This should be fair enough, only it's right in the middle of a massive parking space and means that the rest of the space is now unusable (unless others park their motorbikes there).
I can't decide whether I am being unreasonable. On the one hand, they probably are parked legally. On the other, this is the sort of north London street where parking spaces are hard to come by so parking in a way that means that no one else can squeeze their vehicle in seems quite antisocial.
All the houses are terraced and there are no driveways or marked out parking spaces - you just have to take what you can get on the street.
AIBU?
