I think I can't say anything.
My NDN is very, very ill. She has had a lot of visitors, some regular (like her daughter who lives up the road) and others from further afield.
They nearly all park in such a way I cannot get into my parking space. Well, I could probably get in, but would struggle to get out.
There are a number of visitor parking spaces that they could use, and indeed my car is park in one now (cos I couldn't get into my spot).
I don't mind parking in the visitor spot, but it does mean that there's one less space free for actual visitors or households with more than one car who like to use them (and are free to do so). I can also just go and move my car once the visitor has left but that kind of looks like I'm making a point.
TBH, I'm a bit annoyed that the daughter and her family block me in. Over the years I have had to knock on my DND's door to ask them to move (often when I'm pressed for time). She could very, very easily park elsewhere. I obv can't say anything to my NDN, but if it continues for weeks and weeks WIBU to talk to the daughter. Or shall I just leave it as her Mum is gravely ill?
