I don't want to know of their politics and religion and all the other things I probably disaagree with, but I'd love to be able to give them a cup of sugar if they ran out, or help move a sofa, or all those little things we used to do a bit more for each other.
I think about this often and I agree with you... I genuinely like the idea but then, what do you do if you learn that that neighbour votes for someone who has openly stated that he wants to kill me and my family and people like us? I've never really found the answer to that...
Edit: not in a US political context, just in general
