if someone behaves 'familiar' with you when you don't know them

It's considered suspicious in my culture, like a sign someone wants to induce a feeling of safety in you and scam you. I think it's wise to be wary and watch them closely before you figure out who they are and what they want.
I get greeted in the woods in an informal way by strangers and it's weird but they look harmless, so I don't think too much about it.

It's pretty normal online though. People don't have that many restraints because there's no immediate danger in interactions.

On here, it annoys me at first but I'll go along with it til I decide Nope. But I've made some really good friends in a situation like that.
In real life, I find it sort of creepy so I ease away as best I can.

I found that when we relocated to a rural town. I did enjoy it, but I miss it now.

I see it as someone trying to be friendly. But if it irritates you then letting them know would help… so they can spend that time and effort on someone else that’s open to it.

It’s probably just extra friendly people. I’d prefer that over the opposite.

I find it amusing.

whines* "why does no one like me?" - people act friendly and gets offended lol
