>That’s how you end up with family feuds over centuries because at some point someone did not like someone else.
This is a take it or leave it issue that will come down to personal preference.
The small town mentality knows that this is a possibility, and give it due deference. This is why everyone smiles and nods at almost everyone, almost always. Never cut anyone off. Accept gifts graciously. Mow the elderly neighbors' lawn, put the neighbors' trash out and bring it in if they forget. Do not mention sports, politics, religion, or intimacy unless you are in familiar company, and certainly not if said familiar company holds opposing views.
It does make for a bit of stagnation in that new social trends will always be more slowly adopted, if at all, due to the desire not to offend.
Imagine driving for years on end without anyone ever cutting you off, and people letting you cut if you look to be in a hurry. People offering comfort when you look down. Relative strangers cooking for you when you're sick. All done because they know you to be the kind of person who'd do the same if the situation were flipped because you've shown yourself to be that kind of person.
It's great if you like it, but if it's not for you, it's definitely not for you.
