I really want to just go put something under the wheels but I’ve never talked to these people.
Update edit: thank you for all the replies. I went over and knocked but no answer. It’s definitely not chocked. If I see them come home I’ll go back over. I’m worried as soon as the weight shifts loading it that it will just go down the hill.
Two questions: do you like these people, and is anything anywhere near where it could go if it starts rolling?
I think a more important question is do you actively hate these people?
That’s the only variable that matters. Unless there’s active hatred, there’s no question about whether OP should intervene. Obviously OP should intervene.
This is a trolley problem with zero people on one of the tracks.
Even if you hate these people, that’s an accident waiting to happen and could potentially injure someone completely innocent.
Personally, I’d just buy some chocks and put them there.
No! Don’t fuck with people’s stuff. Just go talk with them.
Chock them if the people are unreachable.
The only reason to make this anything other than a knock on the neighbor’s door is massive social anxiety, and one shouldn’t let that run their life.
