We live in a small cul de sac and so generally people have 2 cars, one on driveway and one on road outside their home. There's no reason for random people to park here so all is fine. At the end of the road is another road where homes have big driveways so when we have guests they park there and walk down (there are only 7 homes up each side so it's 30seconds walk).
We live in the corner of the cul de sac and have no pavement outside our home just the entrance to 3 driveways so nearest pavement is directly outside neighbour's house. First couple of months living here we parked 2nd car at end of the road and walked down but nobody parked on pavement nearest our home so I started to. For about 14 months all was fine but then neighbour mentioned her son had split from fiancé and is moving home so would be parking there. I naively thought she meant whoever gets home first would have the spot so I said something like "oh yes it's the road so I know we don't own it. I'm sure it'll be fine."
Her son is in the forces so not home often and we've carried on parking there but he's now home and she's parking her car there so he can use the drive. I didn't think much of it - yes it's nice to park outside my house with 3dc but they are primary age and capable of walking, although I did notice she's around more than usual (but her son is home so didn't question it).
Other neighbour has just told me that my neighbour has told her how cross she is that we "steal her space" and she's had to change her work hours to ensure she gets home before me so she can get parked there!
I'm planning to ignore the crazy and carry on smiling and calling out hello. Although I don't mind walking down the road, if the space is there then I'll park there. She is a very large lady so I appreciate she cannot walk far but her son is perfectly fit and able late 20s so she can use her drive and he can park and walk 30 seconds occasionally.
Sorry for the essay. I can't imagine changing my working hours for a parking space!
